Main Features

The device is made according to a classic three-detector design and allows for a single sample injection to perform a complete analysis of multicomponent gas mixtures, including H₂, O₂, N₂, CO, CO₂, CH₄, C₂H₆, C₂H₄, C₃H₆, H₂S. The results of the analysis fully correspond to the data obtained on stationary laboratory chromatographs. Thanks to its compact modular design, the device has small dimensions and weight, which makes it easy to transport and carry out analysis directly on site. This allows you to obtain data in a timely and accurate manner with significant savings in labor and material resources. According to the results of tests carried out by the Shandong Institute of Metrology, the device meets the world level in all main characteristics.

Functional Features

1. Fully microprocessor control via touch screen

Supports four-zone temperature control and real-time control of carrier gas flow; digital temperature setting, detector control and overheating protection are implemented.

2. Network management

Built-in 10/100 Mbit/s Ethernet communication technology with automatic negotiation, allowing you to connect devices into a local network with high data exchange efficiency and ensuring data transfer over a remote distance.

3. Multi-detector circuit

With one sample injection, H₂, O₂, N₂, CO, CO₂, CH₄, C₂H₆, C₂H₄, C₃H₆, H₂S and other components are simultaneously determined.

4. Adopting advanced logarithmic amplifier technology.

5. Automatic protection. When pressure or flow goes beyond the established limits, the bridge current is automatically switched off.

6. Automatic flow display and control (EPC)

Electronic flow sensors provide accurate display of carrier gas flow and automatic control of all gas parameters.

7. Memory function

In the event of a power failure or momentary disturbance, control parameters are automatically saved and restored.

8. Protection and self-diagnosis functions

In the event of a short circuit, breakage of the platinum thermal resistance, or excessive temperature, the heating is automatically turned off, indicating the location and type of fault.

9.Easy to operate

Convenient setting of parameters; Everyday use requires only minimal steps to turn the device on/off.

10. Smart start

Built-in touch trigger technology improves retention time accuracy.

11. All components of the device are miniature and housed in a case with a retractable handle, which makes it easy to transport and work in the field.

12. Two power supply methods - AC and DC. Powered by a lithium battery provides up to 8 hours of continuous operation (optional, upon customer request).

Main functionality:

1. Automatic triggering on input peak: automatic switching on of the workstation and chromatograph based on the signal of the sample input peak.

2. Data management: saving analysis results with classification by equipment type; support for equipment information management.

3. Flexible report printing: support for both fixed and user-configurable templates.

4. Automatic fault diagnosis: support for functions of exceeding threshold values, three-component diagnostics (triad) according to GOST, TD diagram, graphs of component concentrations, David's triangle (explosion safety) and other methods.

5. Automatic identification and calibration: support automatic or manual editing of the peak identification table; automatic calculation of calibration coefficients with averaging of the results of multiple calibrations.

6. Trend analysis: visual display of the dynamics of changes in the concentrations of each component based on historical data.

7. Processing of chromatograms: functions for leveling the baseline, splicing (overlaying) chromatograms and others.

8. Real-time bidirectional communication: support full reverse control (reverse control), network control and instrument digital interface.

9. Open data management system: complete preservation of information about equipment and analysis results; support for adding, modifying, deleting, searching, sharing and integrating with other database management systems.

10. Flexible Peak Identification and Processing: Ability to customize parameters, time programs, or manual adjustments to identify, remove peaks, and adjust baselines to ensure accurate analysis results.
