Description

The GC54 gas chromatograph is a high-sensitivity, high-stability, and easy-to-operate food safety testing equipment that can perform precise analysis.

This gas chromatograph is an instrument for qualitative and quantitative analysis of complex mixtures using chromatographic separation techniques and detection techniques. It is commonly used to analyze organic substances that are thermally stable and have a boiling point of not more than 500 °C, such as volatile organic compounds, organochlorine pesticides, organophosphorus pesticides, polycyclic aromatic hydrocarbons, phthalic acid esters, and the like. The system is mainly used in food safety, drug analysis, environmental protection and health and epidemic prevention, agriculture, forestry, fisheries, animal husbandry, manufacturing, petrochemical, quality supervision, teaching research, water conservancy systems and other fields. It is a common instrument for precision analysis and testing in laboratories.

Features of GC54 Gas Chromatograph
* Advanced Microcomputer Control System
•With adoption of advanced control technology, the microcomputer temperature control system is highly precise (less than ±0.05℃), reliable and anti-interfering.
•The system is divided into 5 independent heated zones with maximum temperature up to 400℃. Settable ultimate temperature and overheat protection mechanism ensure a safe operation of the instrument.
•Control and operating parameters can be set on the logical and easy-to-use keypad interface (including detector operating parameters).
•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
•The large column compartment allows for 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 350℃ to 50℃ 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. Constant pressure valve plus needle valve are used in the air and Hydrogen pneumatics for stable gas regulation. 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), are provided for GC54. Different combinations of detectors, in series or parallel operation, can meet different application requirements.
•The novel FID has lower limit of detection, with ejector nozzle and ions collector easily disassembled or cleaned. The fixed and accurate installation structure of the ejector ensures every instrument has consistent performance.
•The high sensitive TCD adopts the high resistant rhenium-tungsten wire, with twofold electronic amplification circuit optional, resulting in maximum sensitivity up to 5000mV·● mL/mg. Its unique air insulation structure brings TCD higher stability of performance.
•Sensitivity and current selections of pulse modulation ECD constant current source are computerized.
