GCOS-6100 Total non-methane total hydrocarbon in ambient air is equipped with direct test non-methane total hydrocarbon analyzer, high purity zero gas generator, high purity hydrogen generator and high precision dynamic calibrator . It can analyze the non-methane total hydrocarbon in ambient air qualitatively and quantitatively.
The sampling pump collects the sample gas from the main air sampling pipe in the micro-heating environment. The sample gas filtered by the high-precision filter dust removal device, and then enters into the non-methane total hydrocarbon analyzer for qualitative and quantitative analysis. The system software can upload the measurement data to the data center according to the national standard communication protocol or the designated protocol.Features:• The cold trap enrichment module is integrated in the direct test method of non-methane
total hydrocarbon analyzer;
• The system is developed based on principle of direct measurement of non-methane total hydrocarbon
by enrichment of thermal in ambient air;
• The system can automatically complete the detection limit, calibration curve, drift and other quality control
indicators detection and generate electronic quality control report, operation and maintenance operation is
very simple and efficient;
• Real-time monitoring of the system gas flow, temperature, flame and other parameters,
automatic fault diagnosis. Prompt, stable, safe and reliable operation;
• It can expand the monitoring functions of meteorological parameters such as ambient air temperature,
humidity, wind speed, wind direction and pressure.
