Description
The Linseis dilatometer L75/120LT was developed to measure the expansion of polymer samples. Hereby up to 8 different samples can be measured simultaneously in a temperature range of –40°C up to +160°C. To cover the temperature range a commonly available climate chamber is used that incorporates a cooling generator and a heat source. The measuring sensors are mounted on top of the heat chamber and connect through a hole into the chamber. The complete arrangement is airtight, in order to avoid the intrusion of humidity into the measuring chamber.
It is possible to insert inert gas into the measuring chamber. The temperature measurement is done by means of 4 type K thermocouples which are hanging always between 2 samples.
This arrangement enables to get a good temperature profile over the measuring chamber. The change of the length of the samples over the temperature change is measured with a LVDT sensor (linear variable differential transformer). This sensor has a very high resolution of 14nm (Nanometer) 10E-9. All 8 LVDTs are connected to the data acquisition / controller parts into the connected computer. The normally used polymer samples can have a length of 80 up to 100mm. The cross-section of the samples can be 4 x 10mm up to 15 x 15mm.
As the used measuring systems are made out of quartz with an expansion coefficient of approx. 5 x 10E-7/K and is thus very small compared to the normal expansion coefficient of the polymer samples, the expansion of the measuring system can be neglected.
For very high accuracy measurements it is possible to use a calibration standard (none thermal expansion) to compensate the influence of quartz glass expansion. The maximum measuring range is +/- 1mm. To measure different sample length (80 up to 100mm) the piston of the measuring system can be adjusted by a motor.
For the zero adjustment the piston will be adjusted by a threat made of invar (invar has a very low temperature expansion at RT) that independent from sample length the core of a transducer (LVDT) is always in the center (zero adjustment).

The Linseis TGA PT1600 for thermogravimetric applications is a toploading Thermobalance, which offers a highly userfriendly design. Even at a sample weight of up to 5/25g the tara is done electronically. The specially designed furnaces allow fast heating and cooling rates as well as a highly precise temperature control. The system can be optionally equipped with a coupling device for EGA (Evolved Gas Analysis). The instrument is highly suitable for thermal composition, thermal stability and oxidation studies.
The (optional) calculated DTA signal provides important additional information regarding endothermal or exothermal reactions. Furthermore it can be used as a tool for temperature calibration.

Unmatched resolution and absolute accuracy is now possible due to the development of the Linseis Laser Dilatometer of the Pico-series. As the name indicates already the resolution goes up to Picometers (0,3 nm = 300 Picometer). That means resolutions can be obtained which are up to a factor 33,33 higher as the resolution that were possible up to date. On top the principle of interference measurement give the possibility for much higher accuracy's, especially as some special computer calibrations are used.

Linseis L75/LASER only needs slight machining of the sample. All you need to do is just prepare one sample, as with the conventional push rod type dilatometer. The system does not require any specific sample geometry. All types of material, reflecting or none reflecting can be evaluated with the system. The measurement principle is an "absolute measurement", not like conventional double sample pushrod Dilatometers, providing much higher precision. No calibration has to be undertake, unlike with conventional Dilatometers.

The Linseis high-pressure dilatometer L75/HP enables completely new applications in thermal analysis. The system can measure expansions (length changes) in the temperature range from RT up to 1100/1400/1800°C and in the pressure range up to 100/150 bar. This device is the world's only available high-pressure dilatometer. A steam generator and camplex gas control system are optional available.

An get even more informations and extend your measeurement, an analysis of the effluent gases can be done by using a QMS or FTIR system at any time. But the coupling is more than only the sum of the separate parts. You can benefit from LINSEIS coupling knowledge and integrated hard- and software concept. For the interpretation of the results, different libraries are available.

Thermogravimetry is a technique in which the mass of the sample is monitored against time or temperature while the temperature of the sample, in a specified atmosphere, is programmed. This technique serves the determination of material compositions.

Simultaneous TGA-DTA/DSC measures both heat flow (DSC) and weight changes (TGA) in a material as a function of temperature or time in a controlled atmosphere. Simultaneous measurement of these two material properties not only improves productivity but also simplifies interpretation of the results. The information obtained allows differentiation between endothermic and exothermic events which have no associated weight loss (e.g., melting and crystallization) and those that involve a weight loss (e.g., degradation).

The LINSEIS High Pressure STA (Simultaneous Thermal Analysis) delivers unsurpassed performance. The system can be used to determine simultaneous changes of mass (TG) and caloric reactions (HDSC) under defined atmosphere and pressure (up to 50/150 bar) in the temperature range -170°C up to 1800°C. This instrument is unique because it is the only available pressure STA worldwide.

The unique characteristics of this product are high precision, high resolution and long term drift stability. The STA Platinum Series was developed to meet the challenging demands of the high temperature and high pressure applications.

Main Application of the High Pressure TGA-DSC:

• Pyrolysis Studies
• Gasification of Coal and Biomass
• Testing of Getter Materials (O₂, H₂, etc.)
• Metal recuction / oxidation studies

The STA PT1600 is the high end Simultaneous Thermobalance from LINSEIS. The system offers unparalleled TG and DSC resolution in combination with the highest vacuum capabilities and TG drift stability. The system is modular with many exchangeable furnaces (-150°C up to 2400°C), different measuring systems and crucibles. The coupling ability and many optional accessories guarantee the perfect setup for every application.

The STA PT 1600 and STA PT1600 HiRes combine both, the sensitivity of a Thermobalance and a true Differential Scanning Calorimeter. Several different TG, TG-DTA and TG-DSC sample holders can be used to determine different reaction and transition temperatures, enthalpies and specific heat. As a result, the system can be perfectly adjusted for any type of application.

Due to the vacuum tight design of the instrument, static and dynamic atmospheres are possible. Optionally a gas control box and a vacuum pump can be connected. The evolving gases can be analyzed with our integrated QMS, FTIR or In-Situ EGA coupling options.

The STA PT1600 HP offers a high pressure ability (up to 5 bar) and many other optional accessories such as Water Vapor generators, Gas Boxes, etc guarantees the perfect setup for many pressure based applications.
With the optional Water Vapor and gas control system, Sorption studies with different gases (water vapor, hydrogen, methane, carbon dioxide, etc) can be performed for example.

The LINSEIS L75 PT Quattro Dilatometer is a very unique instrument, which was developed for customers which have to deal with a large amount of samples. The Quattro Dilatometer is built up with four separate dilatometer measuring sensors, which can measure simultaneously either four separate samples at one time, or three separate samples against a reference standard.

That means, the productivity of the Quattro Dilatometer is three times as high as compared to the normally used dual push rod dilatometers. With a dual push rod dilatometer only one sample can be measured against the standard at each time.

Another feature included in this Quattro Dilatometer is an automatic furnace lift mechanism. This feature automatically lifts the furnace at the end of each measurement without any operator interaction. This allows the user to insert new samples while the furnace is still cooling down, when a second or third furnace is mounted on the system the sample throughput can be even further increased significantly.

The Quattro Dilatometer uses a unique amplifier with automatic zero setting for all four samples. Furthermore there is a “manual push rod speed release” for each sample. With this feature all four samples can easily be changed and seated correctly for high accuracy measurements.

We are proud to say that as far as we know Linseis is the only supplier worldwide, that can offer this highly specialized dilatometer. This is another example of our powerful line of thermal analysis instruments.

Information of the thermo physical properties of materials and heat transfer optimization of final products is becoming more and more vital for industrial applications. Over the past few decades, the flash method has developed into the most commonly used technique for the measurement of the thermal diffusivity and thermal conductivity of various kinds of solids, powders and liquids.

The Linseis LFA 1000 Laser Flash is the most modular and precise Instrument for the determination of Thermal Diffusivity, Conductivity and Specific Heat Values. Its sample robot for up to 6 Samples at the same time allows unbeaten turnaround times. The three user exchangeable furnaces allow measurements from -125 up to 2800°C.

A number of different sample holders for applications such as solids, liquids, melts and slags are available. The compact design allows the separation of hardware and electronics as well as the installation under a hood for nuclear applications.

Thermophysical properties from thin-films are becoming more and more important in industries for products such as, phase-change optical disk media, thermoelectric materials, light emitting diodes (LEDs), phase change memories, flat panel displays and of curse all kinds of semiconductors. In all these cases, a thin film gets deposit on a substrate in order to give a device a particular function. Since the physical properties of these films differ from bulk material, these data are required for accurate thermal management predictions.

Based on the well established Laser Flash technique, the Linseis Laserflash for thin films (TF-LFA) now offers a whole range of new possibilities to analyze thermophysical properties of thin films from 80nm up to 20 μm thickness.

With the magnetic suspension balance LINSEIS MSB PT 1, gravimetric measurements in a wide temperature and pressure range and under aggressive media can be done. Such a magnetic suspension balance consist of a balance for recording the measurement values, a suspension coupling which carries the weight of the sample, a sensor for the position measurement of the levitation part and a control unit to control the suspension coupling.
The contact-less transmission of the sample weight is realized with a levitation magnet and a holding magnet. The levitation magnet consists of a permanent magnet and the holding magnet consists of an electromagnet hanging on the balance. The position sensor delivers the actual position of the levitation magnet and the PID controller makes a stable levitation position with the electromagnetic force as the actuating variable. Through the magnetic coupling a micro balance can be set up at environmental condition. Therefore the balance is protected from high temperatures, pressure and aggressive media.

Metal version

The metal version can be used for a wide application area. Measurements from ultra high vacuum up to 150 bar and a temperature range from -196 to 2400 °C are possible. Furthermore corrosive and toxic media are insertable. This will be possible with special coatings of the metal measurement cell.

Glass version

For the measurements with highly corrosive media, the glass version will be used. Sensitive parts in the measurement cell – for example the levitation magnet and the iron core for the position sensor – are fused-in glass. The functions of the magnetic coupling and of the automatic decoupling correlate with the metal version. The possible temperature is up to 900°C and the pressure range is up to 1.3 bar.

Density

With the Archimedes´ principle the density can also be analyzed with the magnetic suspension balance. A mass with known volume will be weighed. With the buoyancy of the sample the density will be calculated. With a compact construction of the magnetic suspension balance the density can be analysed in a large temperature and pressure range.

The main application field for the LINSEIS L76 Dilatometer series is the CTE measurement of ceramics, brick, tile, porcelain and building materials. Furthermore it is widely used for quality control purposes in ceramics and in metal industries.

Thanks to the fact we started to develop and build Dilatometers in the year 1955, this instrument is very reliable and covers a wide temperature range from RT up to 1000°C, 1400°C and 1600°C with user exchangeable furnaces. It consists of measurement systems made out of quartz glass (up to 1100°C) and Al₂O₃ (up to 1600°C). The sensor is a highest precision LVDT (linear variable differential transformer), which has an indefinite resolution. Together with the 32 Bit software package LINSEIS WIN-TA / WIN-DIL, the Dilatometer provides an excellent solution for standard quality control type CTE measurements.

The following physical properties can be measured:

CTE, Linear Thermal Expansion, Alpha Physical, Sintering Temperature, Phase Transformations, Softening Points, Decomposition Temperatures, Glass Transition Temperatures.

The Quenching/Deformation Dilatometer L78 RITA is especially suitable for the determination of TTT, CHT and CCT diagrams. The special induction furnace enables heating and cooling speeds in excess of 2500°C/s. The system complies with ASTM A1033.

General Information:

This practice is based upon the principle that, during heating and cooling of steels, dimensional changes occur as a result of both thermal expansions associated with temperature change and phase transformation. In this practice, sensitive high-speed quenching dilatometer equipment is used to detect and measure the changes in dimension that occur as functions of both time and temperature during defined thermal cycles. The resulting data are converted to discrete values of strain for specific values of time and temperature during the thermal cycle. Strain as a function of time or temperature, or both, can then be used to determine the beginning and completion of one or more phase transformations.

Main advantaged of the L78 RITA Quenching Dilatometer system:

• The instrument can perform measurements under vacuum, inert, oxidized, reduced atmospheres from 150 (low temperature option) up to 1000°C and room temperature up to 1600°C in one run.
• The unique heating and cooling arrangement enable very fast controlled heat up and cool down speeds of up to 2500°C/s.
• With the optional susceptor non metallic samples can me analyzed.
• This special Quenching dilatometer is especially esigned for the determination of continuous cooling / heat up CHT, CCT and isotherm TTT- diagrams.

All critical parameters such as heat up and cool down speed, gas control and safety features are software controlled. The professional 32-bit software Linseis TA-WIN operates exclusively under the Microsoft© operation system. All routine (creation of CHT/CCT/TTT diagrams) and demanding applications are solved by the unique Software package which comes with the instrument. Certainly export functions in ASCII-format as well as graphic output is possible.

During heating, steel phase transformation of the crystallographic transformation from ferrite, pearlite, bainite, martensite or combinations of these constituents to austenite take place. During cooling, the crystallographic transformations from austenite to ferrite, pearlite, bainite, or martensite or a combination thereof occur. The LINSEIS L78 Quenching Dilatometer

The Optical Research Dilatometer L74 was developed to meet the demanding applications of the glass, ceramics, metal and energy industry. A high resolution CCD camera enables a visual real time analysis of the sample expansion, either as single frame or as video sequences. The big advantage of this method is that the sample is not burdened with any force. For soft samples or samples that melt during the measurement, this leads to a result, which is not distorted by the contact pressure.

Several correction and analysis features are incorporated into the LINSEIS Evaluation Software. The unique horizontal design enables most demanding applications. The special solid-liquid adapter allows expansion / volume measurements of solids, liquids and solid – liquid phase transitions. There is also a special sample holders for measuring rigid foils available, which avoids measurement errors due to pushrod forces like in a classical dilatometer.

The Linseis Transient Hot Bridge - Thermal Conductivity Meter enables thermal conductivity, thermal diffusivity and specific heat measurements on various sample geometries and materials. This Linseis measuring instrument provides the three material properties simultaneously after just a few minutes time regardless of whether you have used the patented sensor in a solid matter (incl. bulk material, gels, pastes) or in a liquid. The preparation of solid samples is pretty simple: One pla-ne surface of two sample halves is sufficient for the sensor. Reference or calibration measurements are a thing of the past. As a matter of course, the THB measures absolute values, with an uncertainty which is not behind that of conventional plate or our laser flash devices.

Different sensors, easily to be exchanged, are available for laboratory and field use. The THB measures fully automatically. Its software control optimizes the measurement process independently, aiming at a short duration and a minimum uncertainty.

Advantages:

• Highest Accuracy
• Absolute technique (no calibration or reference sample required)
• Fast measurement cycles
• Non destructive measurement
• Broad measuring range
• Broad temperature range
• Easy handling (no trained staff required)
• Simple sample preparation
• Applicable for solids, liquids, powders and pastes
• No influence of sensor contact pressure on measurement

Information of the thermo physical properties of materials and heat transfer optimization of final products is becoming more and more vital for industrial applications. Over the past few decades, the flash method has developed into the most commonly used technique for the measurement of the thermal diffusivity and thermal conductivity of various kinds of solids, powders and liquids.

The Linseis XFA 300/600 Xenon Flash offer a cost effective method to measure the Thermal Diffusivity, Thermal Conductivity and Specific Heat Values for up to 6 Samples at the same time.

The modular design of the system enables later upgrade to the sophisticated LINSEIS LFA 1000 system in terms of temperature and Laser Pulse source.

Principle:

The sample is positioned on a sample robot, located in a furnace. The furnace is then held at a predetermined temperature. At this temperature the sample bottom is then irradiated with a programmed energy pulse (Xenon flash lamp). This energy pulse results in a homogeneous temperature rise at the sample top. The resulting temperature rise on the top surface of the sample is measured by a high speed IR detector and thermal diffusivity values are computed from the temperature rise versus time data.
