Product Details

Instrument introduction:

A clear display: Large-screen display makes the display clearer and easier to operate. It can display the path rise curve and the base flow level (the acquisition board needs to be configured), and simultaneously display the temperature setting value and actual value of the oven, the injector, the detector, etc. in one screen, which can provide more colorful Instrument information

High-performance microcomputer temperature control system: It adopts international advanced manufacturing technology, high temperature control precision (better than ±0.05°C), high reliability and strong anti-interference ability; 6 independent temperature control zones, the highest control temperature 400 ° C; limit temperature setting and over temperature protection to ensure the safe operation of the instrument. All Chinese keyboards set various control and usage parameters (including detector operating parameters), which are logical and easy to operate; the instrument has self-diagnosis, power-off protection, detector setting, range, polarity and current setting and display, etc. Function, can accurately display the temperature control set value, actual value, retention and analysis time, etc.

High-performance large-capacity oven: Large-capacity oven can accommodate both capillary column and double-filled column; the oven has rapid heating and rapid cooling, that is, automatic rear door opening mechanism (from 300 ° C to 50 ° C within 10 min, can automatically change according to temperature changes) Adjust the door opening angle), and can realize the quasi-room temperature control. The oven has a 10th order 11 platform program temperature (requires back control software support)

High-precision dual-stabilized gas path: The carrier gas flow path adopts the double-stabilized design of the pressure-regulating valve and the steady-state valve; the air and hydrogen flow path adopts the steady-state regulation mode of the pressure-regulating valve plus the needle-shaped valve, the steady flow valve and the needle valve are all digital. Scale knob with high precision, repeatability, high reliability and convenient flow adjustment

Flexible injection system to meet various analytical requirements: The instrument can be installed with up to three injectors at the same time. According to the analysis requirements, the best injector combination can be selected, and each unit can be independently temperature controlled, and the sampler can be disassembled and assembled. simple. Single packed column / double packed column injector (PIP): can be used to fill the column head injection method, suitable for a variety of columns; add a six-way valve for gas injection analysis; use the connector in the packed column sampler, The 0.53 wide-bore capillary column analysis can be easily performed. Single Capillary Column / Double Capillary Column Sampler (SPL): Dedicated capillary column injector with diaphragm purge and back pressure valve split adjustment for a wide range of capillary columns

High Sensitivity, High Stability Detector: The instrument can be installed with up to three detectors simultaneously, such as FID, TCD, ECD detectors, etc. Depending on the analysis application, different combinations can be used to facilitate the series and parallel operation of the detector. The new FID has a lower detection limit for easy disassembly and cleaning of the spout and ion collection components. The precisely fixed emitter mounting structure ensures a consistently high performance of each instrument. The unique air insulation structure gives TCD a higher stability. High-sensitivity HTCD uses high-resistance tantalum tungsten wire with sensitivity up to 10000mV. mL/mg. Modulated pulsed ECD constant current source, sensitivity and current selection

New built-in acquisition system: Advanced built-in acquisition device that can collect instrument control status and chromatographic output signals, and connect to an external computer with a communication line for real-time control and data processing. (Need to configure anti-control software and acquisition board) Real-time control includes various temperature control, detector selection and setting, program temperature control and temperature-programming curve tracking, flow value display and other functions. Data processing includes dual channel (expandable to multi-channel) high-speed chromatographic data acquisition, automatic or manual setting of integration parameters, up to five quantitative methods, baseline subtraction, report compilation, etc.

Digital carrier gas flow monitoring system: The GI-5000-01 pneumatic system can be equipped with the latest digital flow monitoring unit. The screen displays the carrier gas flow and capillary flow value, and can display up to 4 groups of flow, and the flow parameters can be automatically Storage, easy to analyze the recording and calling of conditions. Convenient for split flow adjustment and split ratio calculation, no need to use soap membrane flowmeter
