Trace gases refer to gases in the atmosphere at very low concentrations, usually below 10E-6, that is, between parts per trillion and parts per million, that are difficult to detect.

The detection and analysis techniques of trace gases are essential for monitoring and protecting the environment and industrial production.

Accurate monitoring and analysis of trace gases is essential. So how can trace gases be detected and analyzed? A trace gas analyzer is the main measuring instrument for the detection and analysis of trace gases.

 

A trace gas analyzer is a high-precision instrument used to detect and measure and analyze the composition of very low concentrations of gases in ambient air or industrial processes. The analyzer has a wide range of applications and values in many fields.

In terms of environmental protection, it can be used to monitor pollutants in the atmosphere, such as carbon dioxide, nitrogen oxides and ozone. By monitoring the concentration of these pollutants in real time, environmental quality can be assessed and necessary measures can be taken to reduce pollution.

Due to the special nature of the trace gas analyzer itself, it needs to be accurately calibrated before it can be put into use.

The 0.5% high precision dilution device is developed for the calibration of trace gas analyzer. The flow rate is controlled by a sonic nozzle. It is the rare high-precision dilution device on the market with a dilution ratio expansion uncertainty better than 0.5% (k=2).

Main Applications

Calibration: Suitable for measurement institutes and calibration institutions, dilute high concentration standard gas to low concentration gas, calibrate trace gas analyzer, or type evaluation;

Period verification: applicable to the use of trace gas analyzer units, dilution of high concentration standard gas into low concentration gas, period verification and functional inspection of the gas analyzer;

Instrument calibration or detection limit test: suitable for trace gas analysis and development units, gas sensor development units, dilution of high concentration standard gas into low concentration gas, calibration instrument or test detection limit.
