Product News for Gas Migration Testing
Liquids or Gases under Pressure Testing Pressure Testing All metal, plastic, and composite parts intended to contain liquids or gases under pressure are required to undergo stringent pressure testing procedures to meet qualification standards. E-Labs can meet our customers' needs for pressure testing using a multitude of different gases over an extended range of pressures. Whether it be proof pressure or burst testing we have the facilities to accommodate large tanks up to 8 ft long and 3 feet in diameter. Rigorous field test... (read more)
KOBOLD Instruments, Inc.
Mass Flowmeter for Gases - MAS KOBOLD ’s MAS Mass Flowmeter measures clean gaseous flow rates in ranges from 0-10 SCCM to 0-500 SLPM. Accuracy is ± 1.5% of full scale over a wide temperature and pressure range. Response time is two seconds to within 2% of final flow. The MAS offers outstanding performance and unsurpassed value. In contrast to volumetric flow metering devices, the MAS requires no pressure or temperature correction. This makes the unit ideal for a wide variety of clean gas flow applications... (read more)

Branch Environmental Corp.
Reduce Undesirable Dissolved Gases! REMOVE C02, RADON, VOC OR OTHER DISSOLVED GASES FROM WATER. You can reduce undesirable dissolved gases with low operating cost using proven Branch Environmental Stripping technology. C02 can be removed using ambient air. Volatile organic compounds can also be readily removed. For more difficult applications such as Acetone, steam can be used for stripping. Steam stripping also allows recovery, in some cases, such as Ammonia. The same type of design is effective in introducing oxygen into water... (read more)
Wilks Enterprise, Inc.
Portable Vapor Monitor for Anesthetic Gases A portable, mid-infrared specific vapor analyzer, designed for easy, on-site measurment of four anesthetic gases, is available from Wilks Enterprise, Inc. The InfraRanTM 4-Gas Anesthetic Specific Vapor Analyzer provides on-site, real-time measurements of Nitrous Oxide (0 - 100 ppm), Desflurane (0 - 50 ppm), Isoflurane (0 - 50 ppm), and Sevoflurane (0 - 50 ppm). The analyzer is ideal for use in hospital operation and recovery rooms, dental offices, and veterinary facilities where it is important... (read more)
Unique System to Blend + Dilute Gases Environics ® Gas Blending and Gas Dilution systems offer the unique capability to blend and dilute gases in a single chassis system. The gas mixes can be used in generating precise gas calibration standards, creating gaseous atmospheres or producing gas mixes for analytical research or production purposes. With an accuracy of +/- 1% and repeatability of +/- .05% of setpoint, the Series 2040 and Series 4020 can provide gas concentrations from percent to parts per billion standards. Series... (read more)
Specifically For Measurement of Fast-Evolved Gases The system features a state-of-the-art integrated interface and analysis system for real-time unequivocal detection of multiple gaseous species to 500 amu, with comprehensive data analysis programs for combined presentation of gas species and gas abundances together with process temperature status, weight change and evolution rates. The quartz internal surfaces of the QIC (Quartz Inlet Capillary) process interface ensure optimum sample integrity, from the sample interface right through... (read more)
Precise Mixing Gases for Clinical Applications! can also be used to create a specific and stable gaseous environment for medical gas mixing or in a clean room. In all cases, the Environics Atmosphere Mixers allow you to use less expensive single-gas cylinders or bulk tanks in place of a high number of expensive blended cylinders. Flexibility: Environics' systems automatically blend and dilute gases to generate precise gas mixes. The Series 2000 dynamically produces complex mixes containing up to eight (8) individual component gases... (read more)
