High precision, uninterrupted

AtmospherIQ Gas Analyzers are designed for high-precision concentration monitoring of atmospheric gases—including CO2, CH4, N2O, CO2 isotopologues, NH3, and H2O. Get the reliable, stable, and WMO and ICOS compatible measurements that gas monitoring requires at an unmatched price.

Together with its superior performance, low maintenance requirements, and a unique power management system, each AtmospherIQ Gas Analyzer is made with your atmospheric monitoring needs in mind.

A trusted legacy with the highest standards

As the second analyzer family in a long line of scientific excellence, AtmospherIQ Gas Analyzers are built on a foundation of trust and expertise. They share a 35+ year history of global research applications and use the same tried-and-true, patented Optical Feedback–Cavity Enhanced Absorption Spectroscopy (OF-CEAS) technology as the LI-COR Trace Gas Analyzers for continuous, reliable measurements with outstanding data quality.

  • Built with trusted OF-CEAS technology
  • Meets WMO compatibility goals
  • Meets ICOS atmospheric stations specifications
  • Offers long-term reliability with minimal downtime

Peerless technology and results

AtmospherIQ Gas Analyzers use OF-CEAS complemented by numerous patented technologies and innovations. The high-finesse optical cavity allows the laser to be reflected through the cavity multiple times, which enhances the signal severalfold.

In addition, a dense grid created by the fixed cavity resonance modes, in combination with tightly controlled cavity temperature and pressure. This allows for high resolution sampling with very low uncertainty. Together, this technology and signal processing let you take very fast and sensitive measurements with the long-term stability that’s expected from laser-based systems.

Figure 1. Simplified schematic of the AtmospherIQ Gas Analyzer flow path through the optical bench. The phase adjuster is a volume in the path between the laser and optical bench that is tied to a pressure control mechanism. Changing the pressure of that volume alters the refractive index which subsequently modifies the phase of the laser.
