The CRDS Gas Analyzer delivers ultra-high purity gas analysis with precision, speed, and reliability. For full product specifications, refer to the Process Insights CRDS analyzer page. Developed by Process Insights under the TIGER OPTICS™ brand, it uses Cavity Ring-Down Spectroscopy (CRDS) to detect moisture, oxygen, and hydrocarbon impurities in real time. Because of its sub-ppb detection limits, it ensures quality control and process assurance in semiconductor, medical, and specialty gas production.
The CRDS Gas Analyzer measures how laser light decays inside an optical cavity filled with the gas sample. The light reflects thousands of times between two highly reflective mirrors. Even tiny impurities absorb part of that light, changing the “ring-down time.” This decay rate directly shows the concentration of each impurity. As a result, users receive fast, stable, and accurate data for gas quality control.
Because the CRDS Gas Analyzer has no moving parts, carrier gases, or consumables, it operates continuously with minimal maintenance. It provides rapid response, high reproducibility, and long-term stability. In addition, its compact solid-state design fits easily into laboratory benches or process systems. Therefore, installation is simple, and ongoing upkeep stays low.
This analyzer supports ultra-high-purity gas monitoring across inert, reactive, and corrosive streams. It enables regulatory compliance and continuous purity assurance in demanding applications.
For complementary moisture measurement in similar applications, see the XTDL Optical Moisture Analyzer, which provides high-precision moisture analysis in challenging gas streams.
For broader process gas analysis applications, technologies such as FT-IR & FT-NIR Process Analyzers can be used where multi-component analysis is required.
By combining proven CRDS technology with robust engineering, the CRDS Gas Analyzer provides accurate, low-maintenance monitoring for demanding gas applications. It helps operators maintain purity, improve yield, and ensure process reliability across every industry.
