The HT8600P Open-Path CH₄/H₂O Analyzer is a fully upgraded version of the HT8600, featuring an innovative dual-component open-path design specifically optimized for CH₄ and H₂O monitoring. Utilizing cutting-edge Quantum Cascade Laser Absorption Spectroscopy (QCLAS) technology, the analyzer leverages multiple laser beam reflections between two high-reflection mirrors exposed to the atmosphere, achieving an effective optical path length of several tens of meters. This allows the instrument to extract the weak absorption of laser energy at the spectral peak and accurately retrieve trace gas concentrations using advanced algorithms. With its high-frequency and high-precision concentration analysis, the HT8600P is ideally suited for measuring net exchange fluxes using 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.

Comparison of Concentration/Flux with another Commercial CH4 Analyzers
Concentration/EC Flux Comparison
The HT8600P and the commercial analyzer show high consistency in measuring methane concentration and turbulent flux, with some variations under different conditions.
Original Flux vs. Corrected Flux Comparison
The HT8600P's original flux and the commercial analyzer's corrected flux display high linearity and consistency. HT8600P offers easier data processing and is less error-prone.
Co-Spectral Density Comparison
The HT8600P's co-spectral density performance is similar to that of the commercial analyzer, showing excellent dynamic response and frequency resolution.
