Main features:
Instrument execution standards: GBl7930-1999 "Unleaded Gasoline for Vehicles", ASTMD3606-1996 "Determination of Benzene and Toluene Content in Vehicle Gasoline and Aviation Gasoline (Gas Chromatography Method)", while meeting JB/T6224-1992 "Laboratory Gas Chromatography" and JJG700-1990 "Gas Chromatography";
Microcomputer based control, high temperature control accuracy (better than ± 0.1 ℃);
The keyboard is used to set various control and usage parameters (including detector operation parameters). The machine has functions such as self diagnosis, power-off protection, file storage and retrieval, limit temperature, and timed on-off temperature control. It can accurately display various temperature control settings, actual values, TCD bridge current, retention and analysis time, etc;
The instrument provides three sets of carrier gas steady flow control. Accurate scale pneumatic control valve components with high reproducibility and stability, capable of directly reading flow values and easy adjustment;
Equipped with a constant temperature flat six way valve for blowback. Optional automatic switching six way valve components controlled by microcomputer timing;
Equipped with automatic cooling and rear door opening function for column boxes, achieving rapid cooling;
The instrument has high separation efficiency and good repeatability. Thermal conductivity detector (TCD) has high sensitivity, low noise, and short stable equilibrium time;
The open microcomputer control system can be equipped with RS-232 interface and FJ-2000 chromatography workstation for bidirectional communication control and data processing;
The large capacity chromatographic column box (300mm × 280mm × 270mm) facilitates the installation of multiple specialized chromatographic packed columns, enabling multidimensional chromatographic analysis.
