The 10m gas absorption cell is applied to spectral analysis and detection of various gases. The light path structure of the gas chamber uses a SlimBoss Gas Cell with excellent optical stability and high-stability optical package structure, which is mainly composed of a gas chamber cavity, a reflector, a standard optical fiber joint, a gas inlet and outlet, and a shockproof base. The unique suspension optical path design has excellent vibration and temperature stability, can work stably in various complex environments, and is very suitable for online real-time detection of various gases. It has low system noise and can be applied to trace gas analysis.
