| Description | The EcoFlex™ Permeation System is designed for creating trace concentration gas mixtures. Mixtures are produced by diluting the minuscule flow of vapor emitted by Trace Source™ permeation (or diffusion) tubes with a much larger flow of inert matrix gas, typically nitrogen or zero air. Mixtures The EcoFlex™ Permeation System is designed for creating trace concentration gas mixtures. Mixtures are produced by diluting the minuscule flow of vapor emitted by Trace Source™ permeation (or diffusion) tubes with a much larger flow of inert matrix gas, typically nitrogen or zero air. Mixtures contact only suitably inert materials, Teflon®, coated stainless steel, or glass.
The EcoFlex™ manual system is built on the same readily transportable platform as the microprocessor controlled FlexStream™ Base Module. The EcoFlex™, however, is a simple, stand-alone, non-expandable, single oven permeation system.
The EcoFlex™ holds the Trace Source™ Permeation Tube(s) at a constant temperature and introduces a small controlled flow of dilution gas over the tube. Pure component compound vapor emitted from the permeation tube(s) mixes with this small flow to form a ‘base’ concentration gas mixture. This base mixture then joins a larger main dilution flow to form the final mixture. The mixture concentration is set by adjusting that main dilution flow.
Permeation tubes of various emission rates are available for over 550 compounds. By choosing a tube suited to the application, mixtures having concentration from low ppb to over 1000 ppm can be generated and the concentration can then be adjusted over a 20:1 range. A single permeation tube, for instance, might be used for concentrations from 1 ppm in 250 cc/min or down to 50 ppb in 5 slpm. Using the mixture immediately after preparation eliminates storage loss....

Permeation tubes require several hours for the emission rate to stabilize after a temperature change. This can be a challenge if the The Model CO395Flex™ Certification Oven is a stand alone version of the permeation tube oven used in the KIN-TEK 491Flex™, Modular Gas Standards Generating System.
Permeation tubes require several hours for the emission rate to stabilize after a temperature change. This can be a challenge if the Gas Generator is used intermittently or switched between applications. The CO395Flex™ is a compact, economical unit designed to maintain permeation tubes in a constantly equilibrated state, ready for immediate use in each application. This feature is especially useful for standards laboratories where the weight loss rate of the tube(s) is continually monitored to insure accuracy, or when permeation tubes are unexpectedly needed to trouble shoot an analyzer. It also saves hours of calibration time by providing pre-heated tubes ready for immediate use.... Read More | KIN-TEK Industrial Gas Standard Generators are used in industrial environments.
