Modular Gas Standards Generator
The 491M/B/SD modular gas standards generator dynamically blends precisely known VOC/TOC gas standards with ppb and ppt analyte concentrations. Two modules provide two sequential stages of dilution. The first stage, 491M/B, combines the analyte flow from Trace Source permeation tubes with a precisely controlled flow of pure dilution gas to form a ppb concentration mixture. In the second stage, 491M/SD, an aliquot of the ppb mixture is further diluted to form a ppt mixture. Trace Source permeation tubes are now available for 500 analyte compounds. The generator uses dynamic blending to circumvent the common problems with ppb and ppt standards, such as unstable ppb and ppt VOC/TOC gas standards in storage due to reactions and adsorption in the container. Dynamic blending avoids this problem. The modular, two-stage dilution approach uses permeation tubes with measurable rates to control analyte flow.
