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.

FEATURED PRODUCT

Cost-Effectiveness Meets Precision

No need for calibration, spare parts, or worries about drift and downtime!

Our TIGER OPTICS™ Spark™ H2O is fast, easy to start up and operate.  For the first time, powerful advanced spectroscopy is available at a popular price for a host of applications, from quality assurance to cylinder filling, as well as welding, medical, industrial and high-purity gas production; bulk delivery and distribution transfer points; and more. Say goodbye to cumbersome, complex, costly and labor-intensive mid-20th century technology. 


 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.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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.
