Detailed product introduction: The gas chromatograph specially used for underground coal mine gas analysis is a multi-functional gas chromatograph specially used for coal mine gas content analysis. The instrument uses an advanced dual-column parallel series thermal conductivity detector, a gas chromatograph with a double hydrogen flame detector in a methane reformer. The process adopts three-signal simultaneous output technology to complete the full analysis of nine gas components in coal mine gas in one injection. It has powerful functions, excellent performance, excellent separation effect, good sensitivity, high reproducibility, simple operation, low failure rate, beautiful appearance, etc. It can fully meet the needs of The multi-task detection and analysis of insulating oil requires all performance indicators to be better than the national standards, making it the first choice for coal mine gas content analysis users.
Performance Features
Super large LCD blue screen with Chinese display and Chinese keyboard input display with rich content and large amount of information. It can monitor various parameters such as temperature and flow in real time.
Implement automatic monitoring of each heating zone and automatically cut off the heating power when the heating zone is over-temperature.
It has a gas cut-off protection function. When the carrier gas pressure is lower than the instrument, it will automatically alarm and cut off the heating power supply and thermal bridge current.
It has a parameter storage function. After the instrument is turned off, you only need to turn on the main power switch when turning it on next time. The instrument will automatically operate in the same state as before the last shutdown, realizing the true power-on function or restoring power after a power outage. The instrument will automatically recover. to the operating state before power failure.
The instrument with fault self-diagnosis function can detect each operating parameter in real time. When the system is abnormal, the microcomputer system will automatically protect the instrument.
The gas circuit system adopts a unique pressure stabilization process design to reduce the impact of pressure fluctuations on the detector during gas injection, thereby minimizing the impact of impact peaks on analysis and ensuring high reproducibility of analysis results. and high accuracy.
The classic three-box design of the whole machine adopts the electrical and gas circuit isolation design to facilitate operation and maintenance, making the appearance of the instrument cleaner and more beautiful, and improving the safety of instrument operation.
