The Gasmet™ Calibrator is used for calibrating new components for the Gasmet™ analyser by generating gases from liquids. It is also used for repeating water calibrations at 12 month intervals. Span calibrations are not needed with the Gasmet™ analysers, since the reference spectra are stored in digital form in the external computer that actually controls the analyser - hence there is no drift. In addition to that, the references are based on a physical constant, the infrared absorption coefficient of the reference gas.
GASMET PORTABLE CALIBRATOR
Gasmet calibrator is one of the most important tools in generating new applications for the Gasmet FTIR Gas Analyzer. The calibrator incorporates a syringe pump, a manual needle valve, a mass flow meter, and a stainless steel injection chamber. The syringe pump injects precise amounts of liquid or gas into a hot nitrogen gas flow, thus producing a continuous flow of a known concentration calibration gas. The injected liquid is vaporized rapidly in the stainless steel injection chamber, which can be heated up to 180 °C, making the calibrator particularly useful when generating high concentration water vapor calibration gas.
By changing the syringe size, the calibrator can be used to produce homogeneous calibration gas from ppm concentrations up to several percentages saturated gas). The GASMET Calibrator is built into a sturdy suitcase. It can be easily transported alongside the Gasmet FTIR Gas Analyzer and the Gasmet Portable Sampling Unit.
