    Testing linearity of Air quality analyzers

    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.

    RATA Relative Accuracy Test Audit or CAL2 (EN14181)

    An important step of CEMS testing is verifying of gas analyzers linearity : this step is well performed with a 30 steps gas divider. With just one test gas reference and a zero gas (diluting gas), the required 5 or 10 scaled concentrations may be easily produced "just in time". 30 steps dilution are available to allow using test gases with concentration up to 3 or 6 times the gas analyzer span.
