CRDS Gas Analyzers

HIGH-PERFORMANCE UHP GAS ANALYZERS | Analyze with Ease™

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.

WHY WE ARE DIFFERENT THAN OUR COMPETITORS

  • Measurement Principle: Our gas analyzers use CRDS technology, which measures the decay rate of light resonating inside a cavity filled with the gas being analyzed. Our competitor’s gas analyzers use Wavelength-Scanned Cavity Ring-Down Spectroscopy (WS-CRDS) technology, which measures the attenuation of light resonating inside a cavity as it passes through the gas sample.
  • Detection Limit: Our CRDS gas analyzers have a lower detection limit than many of our competitor’s gas analyzers, making them better suited for measuring trace levels of gases.
  • Calibration: Our CRDS gas analyzers require calibration using reference gas standards – freedom from the need for span calibrations, while our competitor’s gas analyzers use a built-in calibration system that continuously corrects for drift and other sources of error.
  • Sample Conditioning: Our CRDS gas analyzers require sample conditioning to remove any moisture or other contaminants that may interfere with the measurement. Our competitor’s gas analyzers are less sensitive to sample conditioning requirements.

advantages of OUR CRDS TECHNOLOGY 

  • High Accuracy: Our CRDS gas analyzers are known for their exceptional accuracy, even at trace gas concentrations. This is due to the high precision of the CRDS measurement principle, which allows for accurate measurement of even the smallest changes in gas concentration.
  • High Sensitivity: Are highly sensitive, with detection limits in the parts-per-billion (ppb) range for many gases. This makes them well-suited for applications where low-level detection is critical, such as environmental monitoring or semiconductor manufacturing.
  • Low Maintenance: Designed for easy operation and low maintenance. They are built with a simple, rugged design, and the optics are enclosed in a sealed housing to protect against contamination and damage. Additionally, they require minimal calibration and have a long service life, reducing the need for frequent replacement or servicing.
  • Wide Range of Gases: Can be customized to measure a wide range of gases, including moisture, oxygen, carbon dioxide, methane, and many others. This versatility makes them suitable for a broad range of applications across various industries.
  • Real-Time Analysis: Provide real-time gas analysis, allowing for immediate and continuous monitoring of gas concentrations. This is particularly useful for applications where rapid response times are critical, such as in semiconductor manufacturing or process control.

Because of the many advantages of CRDS, 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.


Announcing that Tiger Optics CRDS Gets CGA Approval

Commodity Specification for Nitrogen

The Compressed Gas Association (CGA) Standard CGA G-10.1 provides guidelines for the verification of gas mixtures used in the semiconductor industry. To comply with this standard, gas manufacturers and semiconductor fabs use gas analyzers to verify the concentration of impurities in the gas mixtures.

Our Tiger Optics gas analyzers were used in the development of the CGA G-10.1 standard to help set performance requirements for gas analyzers used in gas purity verification. Specifically, the high sensitivity and accuracy of the Tiger Optics CRDS (Cavity Ring-Down Spectroscopy) gas analyzers were used as a benchmark for establishing the performance standards for gas analyzers used in the semiconductor industry.

The CGA G-10.1 standard specifies that gas analyzers must meet certain performance requirements, including accuracy, linearity, sensitivity, and stability. Tiger Optics gas analyzers are known for their high performance in these areas, which made them an ideal reference point for the development of the standard. The use of Tiger Optics gas analyzers in the development of the CGA G-10.1 standard underscores the importance of accurate gas analysis in the semiconductor industry, where even small variations in gas purity can have significant impacts on device performance and yield.

PROVEN PRECISION, STABILITY AND RAPID RESPONSE

Our TIGER OPTICS™ Cavity Ring-Down Spectroscopy (CRDS) gas analyzers are used in labs and research applications because they can detect trace amounts of gases at very low concentrations, often in the parts-per-billion (ppb) or even parts-per-trillion (ppt) range. This makes them ideal for analyzing samples that are difficult to detect with other methods, such as atmospheric gases, trace impurities in industrial gases, and contaminants in environmental samples.

In addition, our CRDS gas analyzers are very precise and accurate, with measurement uncertainties typically in the range of 1-2%. They are also fast, with analysis times ranging from a few seconds to a few minutes depending on the gas and the concentration. This makes them ideal for use in real-time monitoring applications where rapid detection and response are required.
