Steady, Stable Gas Delivery
Kin-Tek Laboratories, Inc. (Marque, TX) announces the 491M-PB Module, which is used with 491M Modular Gas Standards Generators to maintain steady gas pressures within the unit and balance backpressure to the delivery system pressure. At trace concentrations (PPM, PPB, and PPT) of reactive gases, surface absorption within the transport system can significantly affect the actual mixture delivered. The 491M-PB eliminates concentration fluctuations by providing a stable reference pressure for all of the mixture flow paths, which is balanced to the system operating pressure to ensure stable delivery.
