CL 203 Cavity Ring-Down Spectroscopy Gas Analyzer (CRDS)
Overview
The CL 203 leverages high-precision Cavity Ring-Down Spectroscopy (CRDS) for ultra-trace gas detection at ppt (parts per trillion) levels—one of the most advanced technologies for precise trace gas analysis.
By measuring the ring-down time of laser pulses within a resonant optical cavity, it detects extremely weak absorption signals. The combination of a long optical path and narrow-linewidth laser ensures precise quantification of gases such as N₂O, CH₄, and C₂H₂—exceeding the capabilities of traditional sensors.
Application Scenarios
