Cavity Ringdown Spectroscopy (CRDS) for Trace and High-Purity Gas Analysis
High-Purity Product Guide - Tiger Optics
Cavity Ring-Down Spectroscopy (CRDS) technology is a highly sensitive and precise analytical technique used for the detection and measurement of trace gases and isotopes in a sample. It is a non-destructive technique that provides quantitative measurements of molecular absorption spectra.
The CRDS technology works by measuring the rate at which light is absorbed by a gas sample contained in a highly reflective cavity. A laser pulse is introduced into the cavity, and the light bounces back and forth between two highly reflective mirrors at the ends of the cavity. As the light bounces back and forth, it is absorbed by the gas sample in the cavity, causing a gradual decrease in the intensity of the light. The time it takes for the light to decay or “ring down” to a predetermined threshold level is measured, and this decay time provides information on the concentration of the gas species in the sample.
CRDS 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, allowing the measurement of specific gas species and isotopes in a complex gas mixture.
TIGER OPTICS™ CRDS analyzers are trusted for detecting moisture and impurities in industrial, medical, and chemical process gases, including inert, reactive, corrosive, and specialty gases.
