The 491M/B/SD Modular Gas Standards Generator blends 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 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.
