Gas Chromatography (GC)

Model: GC-5400
GC-5400 gas chromatograph plays a critical role in quality control of chemistry, medicine and food industries, and also applicable to quarantine, environment protection, quality supervision, oil, petrochemical industry, forensic analysis, agriculture and commodity inspection
Advanced Microcomputer Control System
Temperature control precise less than 0.05C, reliable and anti-interfering.The system is divided into 5 independent heated zones with maximum temperature up to 400C. It has functions of self diagnosis, power-off protection, 10 method files saving and invoking, 2 controls of external events, timing start/stop of temperature control, time programming, detector selection, setting and display of range, polarity and current. The set value, actual value, retention and analysis time of each heated zone can be fully displayed.

High Performance Large Column Compartment
simultaneous accommodation of capillary column and double packed columns. It is equipped with automated back door mechanism, a rapid heating/cooling device (lowering temperature from 350C to 50C in 7 minutes), to realize quasi room temperature control. It supports 5 compartment ramps with 6 plateaus.

High precise pneumatics with dual stability
The carrier gas pneumatics is designed with constant pressure valve plus constant flow valve for dual stability.  Both valves are in form of digital knobs, which delivers high precision, outstanding repeatability, good reliability and intuitive flow rate adjustment.

High-sensitivity and high-stability detector
Up to three kinds of detectors, Flame Ionization Detector (FID), Thermo Conductivity Detector (TCD) and Electron Capture Detector (ECD), in series or parallel operation, can meet different application requirements.
