The main characteristics:
High performance - new design HRGC .
The instrument is equipped with a dual (substrate type) FID Detector, optional GC122-TCD Thermal conductivity detector, GC122-ECD Electron capture detector, GC122-NPD Nitrogen phosphorus detector, GC122-FPD Flame photometric detector and reformer, gas sampling valve and other accessories.
The instrument (type) with double column, double injector, double road system structure, can effectively inhibit the real-time fluctuation and baseline drift, suitable for temperature programmed analysis; instrument can install three kinds of detectors, different applications with different combinations of the detector, and the detector in series and parallel work.
The instrument (type) with complete capillary analysis system, independent of the capillary shunt injector (including membrane cleaning, shunt and tail blowing regulation). Optional capillary split / splitless injector, cold column injector, 0.53mm Large diameter capillary direct injector. Suitable for glass, all kinds of flexible quartz glass capillary column of different diameter, length and specifications.
The instrument gas system with high precision scale type flow stabilizing valve, regulator valve and needle valve. Traffic convenient adjustment, and has a good reproducibility and stability.
The instrument can achieve the following several sampling methods; packed column: column injection, instantaneous vaporization injection, gas injection. Capillary column: split injection, splitless, large caliber capillary column with direct injection.
The microcomputer temperature control system of the new development. At the same time of column box, ionization chamber, thermal conductivity detector, capillary injector, column injector, auxiliary (reserve) to achieve high accuracy a total of six heating zones (better than. 0.1 C Wide range (up to) 400 C ) the temperature control, the temperature overshoot and the deviation is less than 2 C Or less.
The post box can realize the five step program of temperature control, the heating rate reached the highest 40 C /min .
The system has power-off protection, temperature limit setting, temperature scanning, fast automatic door function after cooling.
The microcomputer temperature control system - the open optional RS232 The communication board and FJ-2000 Chromatography workstation workstation and realize bidirectional communication between chromatographic instrument control and data processing.
- high capacity stainless steel box column (350mm * 280mm * 300mm Can be installed at the same time) capillary column and double column; built-in heating wire structure, more conducive to the analysis of quartz capillary column.
