Cavity Ringdown Spectroscopy for Trace and High Purity Gas Analysis
Our TIGER OPTICS™ Cavity Ring-Down Spectroscopy (CRDS) gas analyzers have a long history in industrial gas, medical gas, and chemical processing enabling detection of moisture and other rogue impurities in process gas streams, including inert, reactive, corrosive, bulk and specialty gases.
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.
Our Cavity Ring-Down Spectroscopy (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.

NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY (NIST)
The National Institute of Standards and Technology (NIST) used our TIGER OPTICS HCl analyzer to develop its HCl standards. Our TIGER OPTICS HCl analyzers were used by the National Institute of Standards and Technology (NIST) to develop its HCl standards through a process known as gravimetric preparation. In this process, a known amount of pure HCl gas is diluted with a carrier gas, typically nitrogen, to create a sample with a known concentration of HCl. The sample is then passed through a TIGER OPTICS HCl analyzer to verify the concentration.
By using the HCl analyzer, NIST was able to precisely measure the concentration of HCl in the gas mixture, which allowed them to accurately prepare the HCl standards. The high sensitivity and accuracy of the TIGER OPTICS HCl analyzer ensured that the standards were of the highest quality, which is essential for accurate measurements in a wide range of applications.
In another study, NIST researchers evaluated the performance of a CRDS instrument for measuring methane (CH4) in natural gas samples. They found that the instrument was highly accurate and precise, with a measurement uncertainty of less than 0.1% over a range of concentrations.

HOW WE ARE DIFFERENT FROM OUR COMPETITORS
- Measurement Principle: Our gas analyzers use Cavity Ring-Down Spectroscopy (CRDS), which measures the decay time of light resonating inside an optical cavity filled with the gas that is being analyzed. Unlike techniques used by most of our competitors, this time-based principle allows for absolute accuracy and insensitivity to various noise sources.
- Detection Limit: The absorption enhancement of the optical cavity gives our CRDS systems a lower detection limit than many of our competitor’s gas analyzers, making them better suited for measuring trace and ultra-trace levels gases.
- Calibration: Our CRDS gas analyzers are factory-calibrated against NIST-traceable standards and are free from long-term drift, removing requirements for regular field calibrations, while our competitor’s gas analyzers require recalibration at regular intervals to correct for drift.
- Specificity: Using narrow-linewidth lasers as light sources, our CRDS analyzers are highly specific to the target analyte and are free from most common interferences. Our competitor’s gas analyzers often require sample conditioning to remove interfering species or additional calibration steps to cancel out their effect on the concentration measurement.
