Product Description, Technical Parameters, and Configuration

performance advantage

Clear display screen at a glance

Large screen display, realizing Chinese menu style dialogue, making the display clearer and the operation simpler. It can display the rise curve and base current level (with the need for an acquisition board), and simultaneously display the temperature settings and actual values of the column box, sampler, detector, etc. on one screen, providing more diverse and colorful instrument information.

Excellent microcomputer system with control functions

1A high-performance microcomputer temperature control system using manufacturing technology with high temperature control accuracy (superior to...)±0.05℃）High reliability and strong anti-interference ability; have6An independent temperature control zone with high control temperature up to400℃The extreme temperature setting and over temperature protection function ensure the safe operation of the instrument.

2Set various control and usage parameters (including detector operation parameters) using a fully Chinese keyboard, with strong logic and easy operation; The instrument has functions such as self diagnosis, power-off protection, detector setting, range, polarity, and current setting and display, which can accurately display various temperature control settings, actual values, retention and analysis time, etc.

High performance and large capacity column box

The large capacity column box can accommodate both capillary columns and double packed columns simultaneously; The column box has a rapid heating and rapid cooling automatic rear door opening mechanism（10minFrom within300℃drop to50℃It can automatically adjust the opening angle according to temperature changes and achieve quasi room temperature control. The column box has10step11Platform program heating up (requires support from reverse control software).

High precision dual stable gas path

The air flow path adopts a dual stability design of stabilizing valve and stabilizing flow valve; The air and hydrogen flow paths adopt a stable regulation mode of stabilizing valve and needle valve. Both the stabilizing valve and needle valve use digital scale knobs, which have high precision, good repeatability, high reliability, and convenient and intuitive flow regulation.

Flexible injection system to meet various analysis requirements

The instrument can be installed with up to three injectors at the same time. According to analysis requirements, injector combinations can be selected, and each unit can be independently temperature controlled. The injector is easy to disassemble and assemble.

Single filled column/Double packed column sampler（PIP）：

Can achieve filling column head injection method, suitable for various chromatographic columns; Add a six way valve for gas injection analysis; Using connectors in a packed column sampler can be easily accomplished0.53Wide caliber capillary column analysis.

Single capillary column/Dual capillary column sampler(SPL)：

Specialized capillary column sampler with diaphragm blowing and back pressure valve diversion adjustment, suitable for various specifications of capillary columns.

High sensitivity and high stability detector

The instrument can install up to three detectors simultaneously, such asFIDTheTCDDetector, etc.

By using different combinations according to different analysis applications, it is easy to achieve the series and parallel operation of detectors.

new-typeFIDWith lower detection limits, it is easy to disassemble and clean the nozzle and ion collection components. The precisely fixed emitter installation structure ensures high consistency in the performance of each instrument.

Air insulation and thermal insulation structureTCDHas higher stability.

high sensitivityHTCDUsing high resistance rhenium tungsten wire, with high sensitivity up to10000mV﹒mL/mg.

New built-in acquisition system

Excellent built-in acquisition device that can collect instrument control status and chromatographic output signals, enabling real-time instrument control and data processing by connecting to an external computer through a communication cable. (Need to configure anti control software and acquisition board)

Real time control includes functions such as temperature control, detector selection and setting, programmed temperature rise control and curve tracking, flow value display, etc.

Data processing includes high-speed acquisition of dual channel (expandable to multiple channels) chromatographic data, automatic or manual setting of integration parameters, and up to5Functions such as quantitative methods, baseline deduction, and report preparation.

Digital carrier gas flow monitoring system

GC5400The pneumatic system can be optionally equipped with a new digital flow monitoring unit, which displays the carrier gas flow rate and capillary branch flow rate values on the screen, with multiple options for display4Group traffic, and traffic parameters can be automatically stored for easy recording and calling of analysis conditions. Convenient diversion adjustment and diversion ratio calculation, without the need for soap film flow meters.
