Portable gas chromatograph vehicle mounted rapid mine safety gas detection

Portable chromatograph car mounted fast mineSafe gas detection can timely detect and analyze common gases, including oxygen, nitrogen, carbon monoxide, carbon dioxide, methane, ethane, ethylene, acetylene, propane, and butane To provide decision-making basis for rescue command, scientific and effective data for rescue personnel, and to timely and accurately detect the content of common toxic and harmful gases underground.

Real time automatic underground gas collection on the groundOnline gas analysisNo need for manual sampling (this feature is optional)

Remote automatic sampling distance exceeding 2km (this function is optional)

The movable trolley system facilitates quick and easy movement of the host (this feature is optional).

◆ Three stainless steel packed columns are used to effectively prevent cross contamination of chromatography columns and ensure long-term uninterrupted operation of the entire instrument

◆ Ten way valve injection device, capable of analyzing multiple gases in one injection: O2, N2, CO, CO2, CH4, ethane, ethylene, acetylene, propane

Fast analysis speed: Within 4-8 minutes, a single injection can complete the analysis of the gas constant of mine gas explosion.

Equipped with a 2-liter gas cylinder, easy to carry and arrive at the rescue site in a timely manner.

Equipped with an automatic gas sampler, it shortens the sampling time.

◆ Equipped with a mine gas analysis chromatography workstation, it can set alarm values for various gas concentrations and alkene ratios, and automatically alert for methane and oxygen concentrations entering the gas explosion triangle. The results of both automatic and manual injection can be stored in the database. In the database, historical data or trend charts can be printed (or queried) by time or sampling location, and the distance between gas explosion triangles and historical data can be displayed.

◆ It can achieve online automatic analysis, and through the installation of pipeline instruments, it can automatically sample on a periodic basis. It can monitor and calibrate the process sample gas continuously without the need for manual calibration. In areas where the pipeline probe has not been installed, manual sampling and testing can be used, which is flexible and reliable
