Advanced microcomputer system, excellent control function
The excellent performance of the microcomputer temperature control system adopts international advanced control technology, high temperature control precision (better than ±0.05 °C), high reliability and strong anti-interference ability; 5 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 machine has self-diagnosis, power-off protection, 10 method file storage and recall, 2 external event control, Temperature control timing start and stop, time program, detector setting, range, polarity and current setting and display functions, can accurately display the temperature control set value, actual value, retention and analysis time.
Flexible sampling 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 instrument can select the best injector combination, and each unit can be independently temperature controlled, and the injector can be easily assembled and disassembled.
Single packed column / double packed column injector:
It can be used to fill the column head and is suitable for a variety of columns; add 6-port valve for gas injection analysis; use the connector in the packed column injector to easily complete 0.53 wide-bore capillary column analysis.
Two capillary column injection systems are available, all suitable for capillary columns of various sizes:
a) Dedicated capillary column injector with diaphragm purge and backpressure valve split adjustment.
b) Dedicated capillary column split/splitless injector, independent carrier flow path and makeup flow path, with diaphragm purge and back pressure valve split adjustment, inlet purge solenoid valve, and capillary column split/no by programming time program Split injection.
High sensitivity, high stability detector
The instrument can be installed with up to three detectors at the same time, 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 collector. The precisely fixed emitter mounting structure ensures a highly consistent performance of each instrument.
High-sensitivity TCD uses high-resistance tantalum tungsten wire and provides 2x electronic amplification circuit with sensitivity up to 5000mV•mL/mg. The unique air insulation structure makes TCD more stable.
Modulated pulsed ECD constant current source, sensitivity and current selection are computerized.
High precision double stable gas path
The carrier gas flow path adopts the double stability design of the pressure regulating valve and the steady flow valve; the air and hydrogen flow path adopts the stable regulation mode of the pressure regulating valve and the needle valve, and the steady flow valve and the needle valve adopt the digital scale knob, which has high precision. Good repeatability, high reliability and convenient and intuitive flow adjustment.
High performance large capacity oven
The large-capacity oven can be easily installed and can accommodate both the capillary column and the double-filled column; the oven has a quick heating and rapid cooling, that is, an automatic rear door opening mechanism, and can realize quasi-room temperature control, and the oven is programmed to warm the 5th-order 6 platform.
A variety of free accessories, installation worry-free
The instrument provides a full range of accessories for initial installation, such as purifiers, external air lines, wrench tools, injection needles and various types of connectors. Users only need to prepare the air supply. There is no additional charge for the above attachments.
Rich data processing system, let you choose freely
a) Built-in data acquisition board, using workstation software to perform base flow monitoring, single column compensation, and chromatographic data processing on the computer;
b) A chromatographic workstation consisting of a completely independent dual-channel external data acquisition box and intelligent software, which can simultaneously acquire fast and accurate chromatographic data processing whether it is a floating signal or a ground signal;
c) RS232 communication board and software, connected with the workstation to realize two-way communication and back control with the host, that is, complete temperature, detector parameter setting and monitoring, and data processing parameter setting on one computer;
d) Unique chromatographic simulation software, which simulates the best operating conditions of the chromatogram on the computer, provides chromatographic simulation teaching and training, and chromatographic knowledge base.
