Applications

  • Gas Quality Control
  • High-Purity Gases & Systems
  • Research & Development
  • Semiconductor Process Tools
Detection and Matrix Range* LDL (3σ) Precision (1σ) @ zero
CO2 in N20 – 0.4 ppm100 ppt35 ppt
CO2 in He0 – 0.4 ppm90 ppt30 ppt
CO2 in Ar0 – 0.4 ppm90 ppt30 ppt
CO2 in O20 – 0.4 ppm90 ppt30 ppt
CO2 in Clean Dry Air (CDA)0 – 0.4 ppm100 ppt35 ppt
*Higher range is available upon request.   
Due to the high abundance of CO2 in air,
purging of the analyzer housing is required
to achieve specified LDL (see previous page
for purge gas requirements)
