Product description, technical parameters and configuration

Performance advantages

Clear display

The large-screen display realizes the Chinese menu-style dialogue, which makes the display more clear and the operation easier. It can display the rising curve and the base current level (the acquisition board needs to be configured), and the temperature setting values and actual values of the oven, sampler, detector, etc. can be displayed at the same time in one screen, which can provide more colorful images. Instrument information.

Advanced microcomputer system, excellent control function

1. High-performance microcomputer temperature control system adopts international advanced manufacturing technology, high temperature control accuracy (better than ± 0.05 °C), high reliability, strong anti-interference ability; 6 independent temperature control zones, highest control Temperature up to 400 °C; limit temperature setting and over-temperature protection function to ensure the safe operation of the instrument.

2、All Chinese keyboard set various control and use parameters (including detector operating parameters), strong logic, easy to operate; instrument with self-diagnosis, power protection, detector settings, range, polarity and current settings and Display and other functions can accurately display the temperature control settings, actual values, retention and analysis time of each way.

High performance large capacity oven

Large capacity oven can accommodate capillary column and double packed column at the same time; oven has rapid heating and rapid cooling, ie automatic rear opening mechanism (from 300°C to 50°C within 10min, can automatically adjust opening angle according to temperature change), and Quasi-room temperature control is achieved, and the oven has a 10th-order, 11-platform program temperature ramp (reverse control software support required).

High-precision double stable gas path

The carrier gas flow path adopts the double stabilizing design of the steady voltage valve and the steady flow valve; the air and hydrogen flow path adopts the stable regulation mode of the pressure-regulating valve plus the needle valve; the steady flow valve and the needle valve adopt the digital scale knob and has high precision. Good repeatability, high reliability, and easy and intuitive flow adjustment.

Flexible sample introduction system to meet various analysis requirements

The instrument can install up to three samplers at the same time. According to the analysis requirements, the best sampler combination can be selected. Each unit can independently control the temperature, and the sampler can be easily assembled and disassembled.

Single Packed Column / Double Packed Column Sampler (PIP):

The column head injection method for packed column heads can be used for a wide range of columns; six-way valves can be added for gas injection analysis; the use of connectors in packed column injectors can easily perform 0.53 wide-bore capillary column analysis.

Single capillary column/double capillary column injector (SPL):

Dedicated capillary column sampler with diaphragm bleed and back pressure valve shunt adjustment for a wide range of capillary columns.

High sensitivity, high stability detector

The instrument can install up to three detectors at the same time, such as FID, TCD detectors and so on.

According to different analysis applications using different combinations, the serial and parallel operation of the detector can be conveniently implemented.

The new FID has a lower detection limit, allowing easy removal and cleaning of the spouts and ion collection components. The precise fixed emitter mounting structure ensures the consistent performance of each instrument.

Unique air insulation structure makes TCD more stable.

High-sensitivity HTCD uses high-resistance thorium tungsten wire with sensitivity up to 10000mV. mL/mg.

New built-in acquisition system

The advanced built-in acquisition device can collect the instrument control status and chromatographic output signals, realize the connection of an external computer with a communication cable, and carry out real-time control and data processing of the instrument. (Need to configure anti-control software and acquisition board)

The real-time control includes various functions such as temperature control of various ways, selection and setting of detectors, temperature increase control of the program, temperature-program curve tracking, and flow value display.

Data processing includes dual-channel (expandable to multi-channel) high-speed chromatographic data acquisition, automatic or manual integration parameter setting, up to 5 quantitative methods, baseline deduction, and report preparation.

Digital carrier gas flow monitoring system

The GC5400 gas system can be equipped with the latest digital flow monitoring unit. The carrier gas flow rate and capillary flow rate value can be displayed on the screen. Up to four groups of flow rates can be displayed, and the flow rate parameters can be stored automatically, facilitating the recording and recall of analysis conditions. Convenient for split flow adjustment and split ratio calculation without the use of a soap film flow meter.
