Thermo Fisher Scientific nitrous oxide analyzer measures from 50 to 4,000 ppb

The IRIS 4600 mid-IR laser-based nitrous oxide analyzer uses mid-IR laser absorption spectroscopy to simultaneously measure nitrous oxide and water vapor concentrations, allowing calculation of the nitrous oxide dry-mole fraction at sub-ppb levels. The analyzer can make measurements in the 50 to 4,000 ppb range.

PRESS RELEASE

Thermo Fisher Scientific Announces New Laser-Based N₂O Analyzer

Increased Measurement Capabilities for Greenhouse Gas Monitoring

FRANKLIN, Mass. – Thermo Fisher Scientific Inc., the world leader in serving science, today announced the new Thermo Scientific IRIS 4600 Mid-IR Laser-Based Nitrous Oxide (N₂O) Analyzer. The IRIS 4600 Mid-IR Laser-Based N₂O Analyzer uses a laser module developed by the recently acquired NovaWave Technologies, Inc, and combines it with proven Thermo Scientific air quality monitoring technology to create the most precise analyzer on the market.

Nitrous oxide is one of the primary greenhouse gases with a greater potential for global warming effects than carbon dioxide (CO₂). The IRIS platform of analyzers is designed for use in monitoring key greenhouse gases (GHG) such as methane and nitrous oxide.

The IRIS 4600 Analyzer uses state-of-the-art mid-infrared laser absorption spectroscopy to simultaneously measure nitrous oxide and water vapor concentrations with high precision and accuracy. Continuous measurement of nitrous oxide gas and water vapor allow for the calculation of the nitrous oxide dry-mole fraction at sub-ppb levels. The analyzer is capable of making measurements in the range 50 to 4,000 ppb.

“For nitrous oxide in particular, monitoring concentrations at the 3-micron band is highly desirable, as the associated absorption intensity is nearly 100-times stronger than those of the more commonly used 1.5 micron overtone bands,” said James Scherer, director, business development, Thermo Fisher. “Additionally, the DFG laser platform leverages telecom commodity technologies instead of MIR approaches, which have yet to find high-volume applications. As such, the sensor can be manufactured with high yield, reproducibility and reliability.”
