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)
Control Instruments Corp.
Monitoring Combustible Gases in Kilns A new white paper by Control Instruments, "Monitoring Combustible Gases in Kilns," discusses the hurdles involved with monitoring combustible gas concentrations for safety and key points to consider. Heating all sample?wetted parts of the analyzer and sampling system to 250 °C will prevent condensation. The sample stays intact. The measurement includes all combustible vapors. Sample pumps cannot provide the same level of reliability as an aspirated sampling system and should be avoided... (read more)
Branch Environmental Corp.
Columns for absorbing or stripping gases Aeration Columns. Branch designs and builds custom fabricated mass transfer equipment for gas absorption and removal. The most common types of aeration devices we provide are: •Packed Columns for either absorbing or stripping gases. •Tray Column. In water service applications, air will saturate incoming water as it moves vertically downward through the columns. Volatile gases trapped in the water are released into the air as the water contacts the high surface packing media. Units can... (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)
Connectors for fluids, gases and electrics Selecting connectors for fluids, gases and electrics. Modern machinery and equipment often requires connections not just for electric power, hydraulics, cooling fluids and pneumatics but frequently also data transfer, fibre optics, sensors and thermocouples. How can all of these connections be made in one simple operation?. What types of connections are required?. Frequently on modern machinery there is a requirement to connect not only the fluids and pneumatics that are needed to operate... (read more)
Safely Dilute/Mix Explosive Gases purge flows through the enclosure while it is running. This serves two purposes. The first is to carry out heat built up by the internal components. The second is to dilute any potential leaks that may develop. The gas plumbing inside this enclosure was vacuum leak tested to 1X10-8 ATM CC/SEC He. In addition to continuous purge flow, the enclosure is pressurized to approximately 5 ” H20 while running the enclosure purge. This provides and indicator that the purge is activated as well...

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 Blends + Dilutes 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)
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)
