Overview

The measurement of greenhouse gas emission fluxes is an important subject in atmospheric environment science. It is the basis for studying the variation trend, sources and sinks of greenhouse gas concentrations, and is of great significance for assessing the distribution of greenhouse gases and coping with climate change. Understanding the change of the exchange flux between earth and air over time, understanding the exchange of global greenhouse gases, and long-term observation of the flux of different ecosystems play an important role in revealing the absorption and release process of greenhouse gases such as CO2, CH4, NH3, N2O, SF6 in the atmosphere, energy flow and material circulation, and the interaction between the surface biosphere and atmosphere.

Principle

LGHS-001 series greenhouse gases monitoring system, consisting of trace level photoacoustic spectroscopy multi-gas analyzer , scalable programmable multi-point sampler, sampling chamber, sampling pipeline, special analysis software. It has the advantages of high measurement accuracy, low detection limit, good real-time performance, testing at the current point, high-efficiency measurement, etc. It is a reliable solution for online or mobile observation and analysis of greenhouse gas fluxes.

The system analyzer is based on infrared photoacoustic spectroscopy technology, has a pulsed infrared light source, and forms 10 spectral bands in the mid-infrared region through narrow-band optical filters for gas analysis. The ultra-high sensitivity is based on the patented enhanced cantilever beam optical microphone technology, which can be realized by 10 kinds of optical narrow-band filters, and the extremely narrow optical filter can remove the interference of background gas. Multiple spectral regions can facilitate minimal cross-sensitivity. The system analyzer can detect more than 300 kinds of gases.

The LWS001 multi-point sampler can freely expand gas sampling points from 12 channels to 60 channels. The instrument can be used for micro-flow gas sampling and high-temperature gas working conditions.
