LGA-400 In-suit Ammonia Laser Analyzer

The LGA-400 In-suit Ammonia Laser Analyzer is an In-suit extraction-type analysis system independently designed based on the TDLAS technology platform. This system adopts multi-reflection technology to increase the measurement optical path length and utilizes in-situ high-temperature hot-wet extraction methods to measure gases such as NH3, HCl, HF, and H2S.

The full-temperature heating ensures effective prevention of condensation during the sampling process, which would cause corrosion and blockage in the analysis system. It enables continuous and stable operation for high dust, humidity, and corrosion environments.  The system has advantages of low detection limits, high accuracy, convenient calibration and comparison, no moving parts, simple and compact structure, high reliability.

Features

•   The filter can be easily removed and replaced

•   Multiple reflection technology.  Low detection limit

•   Laser spectroscopy measurement. High accuracy and stability

•   Equipped with a high-temperature flow meter, allows on-site monitoring of the gas flow rate;

•   In-suit installation with single flange. No need to use heated sampling line. High integration, easy installation

•   Suitable for application of vibration condition, eg. vessels

•   High-temperature sampling, strong adaptability. Not affected by the irregular shape of the pipeline, high dust     concentration, or working condition changes.

•   Full process heated at around 180 ℃.  Automatic back purging.  Avoid the blockage caused by high dust and     ammonium salt crystallization. Long maintenance interval

•   Explosive-proof version available
