New 491M/B/SD modular gas standards generator dynamically blends precisely known VOC/TOC gas standards with parts-per-billion and parts-per-trillion analyte concentrations.
Two modules provide two sequential stages of dilution. The first stage combines analyte flow from Trace Source permeation tubes (offered for up to 500 analyte compounds) with precisely controlled flow of pure dilution gas to form a ppb concentration mixture. The second stage, an aliquot of the ppb mixture, is further diluted to form a ppt mixture.
