Testing linearity of Air quality analyzers - Environmental - Environmental Monitoring
To test gas analyzers for Air Quality monitoring, gas references must have concentration in the range of hundreds to tenths ppb. Test gas bottles with so small concentrations are expensive and unstable. With the gas divider BetaCAP30X100 it's possible to dilute high concentration test gases getting 30 dilution steps in the range from 1:100 to 1:3.000 of the original test gas bottle concentration. Traditionally MFC based diluters are used for this application, but now our capillaries based diluter is available, with more stable performances.
