Features:
1. High accuracy
The sample was analyzed for high-temperature heat tracing, and no loss of sample was observed during the analysis.
Gas chromatographic detection, analytical methods in line with national standards, accurate measurement;
The use of electronic pressure flow control technology (EPC, EFC) to control the carrier gas, air and hydrogen, respectively, guarantees high repeatability and high accuracy of analysis.
2. Qualitative and diverse
By increasing the flow path and single cycle, simultaneous detection of non-methane total hydrocarbons, benzene, toluene, and xylene can be achieved.
3. Stable and reliable
Full electronic flow control (EPC), stable and reliable;
FID detector has automatic ignition and temperature judgment function. After the FID flame goes out, it automatically shuts off the flow of hydrogen and air to ensure the safety of the system.
The core components use well-known foreign brands of devices for high reliability and long life.
4. Real-time monitoring
The single cycle time is less than 90s to ensure real-time monitoring.
5. Highly intelligent
Regular automatic calibration and calibration;
Touch screen man-machine interface, simple operation, easy to use;
Fully automatic operation, unattended. Technical Parameters:
