The Mingqin GCD-9200 portable VOCs monitoring instrument adopts gas chromatography separation technology and hydrogen flame ionization detection (FID) technology to achieve qualitative and quantitative monitoring of total hydrocarbons, methane, and non methane total hydrocarbons in pollution source exhaust gas.
Product principle
Separate methane, non methane hydrocarbons, and benzene derivatives in the sample gas using gas chromatography. After separation, the gas is sent to a hydrogen flame ionization detector (FID) for combustion, and the concentration of VOCs is determined by measuring the ion current.
Product advantages
1. High integration
The chromatographic analysis module, FID detector, battery module, hydrogen cylinder, standard gas cylinder, and electronic automatic pressure control module are all integrated into one analyzer host system. The highly integrated design makes on-site operations more efficient and fast.
2. More reliable detection data
◆The sample adopts a full process high-temperature tracing method to avoid condensation of the sample;
◆The automatic flame detection function can detect the real-time status of the flame, ensuring the normal operation of the instrument;
◆Adopting electronic design, the pressure and flow control module can control the gas path;
◆ It has manual/automatic calibration function, providing calibration of standard gas and zero gas, blowing and cleaning of the operating gas path, and dual standard curves are available for selection and can be reset by oneself;
◆The temperature of the heat tracing tube can be automatically adjusted according to the sampling port temperature to prevent VOC gas condensation and system errors.
3. Friendly human-computer interaction
◆ Chinese operation interface, the device comes with real-time monitoring of instrument operating parameters, and has equipment fault diagnosis function to quickly diagnose and maintain equipment faults, ensuring the normal operation of the instrument.
The device can automatically process/store data and spectra, and display monitoring parameters in real-time. For example, providing historical spectra and alarm information queries for box temperature, pressure parameters of various EPC modules, FID temperature parameters, and gas pressure parameters.
4. Multiple filtering to prevent blockage
During the sampling and intake process, a triple filtration design is adopted to prevent particles, oil fumes, ink, water vapor, and other blockages in the air path.
5. Low maintenance costs
The battery can be recharged and discharged repeatedly with low power consumption during sleep mode; Consumable components support separate replacement.
6. Innovation breakthrough
PID algorithm single loop control can accurately adjust the EPC electronic pressure control module;
◆ Customizable personal detection parameters to achieve customized detection tasks;
The sampling head is equipped with a stable current testing pipeline to monitor the temperature, pressure, and flow rate of the discharge outlet in real time;
Unique patented technology ensures stable ignition with a success rate of over 99%.
