TIGER OPTICS™

Cavity Ring-Down Spectroscopy (CRDS) technology from Process Insights is a highly sensitive and precise analytical technique used for detecting and measuring trace gases and isotopes in a sample. It is a non-destructive technique that provides quantitative measurements of molecular absorption spectra.

CRDS technology operates by measuring the rate at which light is absorbed by a gas sample contained within a highly reflective cavity. A laser pulse is introduced into the cavity, where the light bounces back and forth between two highly reflective mirrors at the ends of the cavity.

This technology is highly sensitive, capable of detecting trace levels of gases and isotopes at parts-per-billion (ppb) or parts-per-trillion (ppt) concentrations. It is also highly selective, enabling the measurement of specific gas species and isotopes in a complex gas mixture.

In 2001, TIGER OPTICS™ CRDS gas analyzers became the first commercial Cavity Ring-Down Spectroscopy (CRDS) analyzers available on the market. Today, these CRDS gas analyzers monitor thousands of critical points for industrial and scientific applications. They serve the world’s national metrology institutes, functioning as transfer standards for the qualification of calibration and zero gases.
