GC-4095 portable gas chromatograph for coal mine Introduction
GC-4095 coal mine portable gas chromatograph, mainly used to analyze the multi-component of the air composition under the mine, can be used to analyze the full composition of the mine gas on the mine site, or used for laboratory analysis, early prediction Predict coal seam spontaneous combustion, monitor the change of gas component concentration during coal spontaneous combustion to prevent spontaneous combustion and gas explosion.
When the instrument is used for on-site analysis of mine operations, on-site direct sampling is used, without the need for auxiliary sampling by other equipment. After sampling, only the six-way valve needs to be switched to complete the sampling. Features
The instrument technology is advanced, the design is reasonable, and it is convenient to carry;
The analysis gas components are: oxygen, nitrogen, methane, ethylene, ethane, acetylene, carbon monoxide, carbon dioxide and other components;
Using high-precision gas thermal conductivity sensor, using silicon micro-technology, low power consumption, wide temperature range, high sensitivity, low detection limit, high detection accuracy;
Light weight, compact size, novel design, self-contained carrier gas cylinder, self-contained rechargeable lithium battery, suitable for emergency monitoring and on-site analysis;
Low working environment requirements, only need to stabilize the instrument without heating at room temperature;
The design of the instrument is reasonable, and the six-port valve is used for sampling, and the gas content of multiple components in the mine can be analyzed at one time;
The analysis period is short, the full analysis is not more than 13min;
Easy to apply, only one kind of gas is needed as carrier gas, no fuel gas or fuel gas is needed;
Non-destructive testing, secondary analysis and testing of the gas to be tested;
The operation is simple. After rotating the six-way valve to inject the sample, the instrument automatically starts to start peaking, and stops automatically when all components are detected, and directly obtains the content report without processing;
The instrument has a built-in memory card. Connect the computer with a USB extension cable. The memory card of the instrument can be found on the computer, and the data file "* .txt" marked with the file name can be queried and opened on the computer. Query the concentration data of each component with different sampling numbers;
With the A5000 workstation of our company, the instrument data can be transferred into the workstation system for more convenient data processing and analysis.
