HT8600 Open-path CH4 Analyzer

The HT8600 open-path atmospheric CH4 (methane) analyzer utilizes the state-of-the-art Quantum Cascade Laser Absorption Spectroscopy (QCLAS) technology. The product relies on the laser beams multiple reflections between two high-reflection mirrors exposed to the atmosphere, creating several tens of meters of an effective optical path length. The weak absorption of the laser energy at the spectral peak is extracted, and the trace gas concentration is retrieved based on innovative algorithms. The high-frequency and high-precision concentration analysis makes the HT8600 very suitable for measuring the net exchange flux based on the Eddy Covariance technique.

Based on the R&D experience of the HT8700 NH3 Analyzer, we have established many partners in China and the European Union. Please find a customer case at - AFM: Scientists Develop a New Instrument to Measure Atmospheric Ammonia.
