Audited Supplier GC1120 Gas Chromatograph Testing Equipment
GC1120
1-Human-machine interface
-Large LCD display, dialog box operation, Synchronous display the temperature set value and real value in same screen of Column box, injector, detector.
-Microcomputer temperature control system, with 6 independent temperature control zones, with limit temperature setting and overtemperature protection functions.
-Keyboard setting control and usage parameters (including detector operating parameters); The instrument has functions such as self-diagnosis, power-off protection, detector setting, range, polarity, and current setting and display.
2-Column temperature box
A 10min high capacity column box can accommodate both capillary columns and dual packed columns; The column box has an automatic door opening mechanism after heating and cooling ( 300 ºC drops to 50 ºC, and the door opening angle can be automatically adjusted according to temperature changes). The column box has a 10-step 11 platform program for temperature rise.
3-Dual stable gas path
-The carrier gas path adopts a dual stability design of a pressure stabilizing valve and a flow stabilizing valve; The air and hydrogen flow paths adopt a stable regulation mode of a pressure stabilizing valve and a needle valve. Both the pressure stabilizing valve and the needle valve adopt digital scale knobs
4-Flexible injection system
-The instrument can be installed with up to three injectors at the same time. According to analysis requirements, a good injector combination can be selected, and each unit can independently control temperature. The disassembly and assembly of the injector is simple.
-Single packed column/dual packed column injector (PIP).
-It can realize the filling column head injection method and is suitable for various chromatographic columns; Add a six way valve for gas injection analysis; Using connectors in a packed column injector can easily complete 0.53 wide bore capillary column analysis.
-Single capillary column/dual capillary column injector (SPL).
-Capillary column injector with diaphragm purging and backpressure valve shunt adjustment, suitable for capillary columns of different specifications.
5-Detector
-The instrument can be installed with up to three detectors simultaneously, such as FID, TCD, and ECD detectors.
Adopt different combinations according to different analytical applications, which can easily achieve series and parallel operation of detectors.
The FID detector can easily disassemble and clean the nozzle and ion collection components.
HTCD adopts rhenium tungsten wire with high resistance value, with a sensitivity of 10000 mV · mL/mg.
Modulated pulse type ECD constant current source, with microcomputer based sensitivity and current selection.
6-Built-in collection system
Built-in collection device, which can collect instrument control status and chromatographic output signals, and realize real-time control and data processing of the instrument by connecting an external computer with a communication cable.
Real-time control includes various temperature control functions, detector selection and setting, programmed temperature control, and programmed temperature curve tracking.
Data processing includes dual channel (expandable to multiple channels) chromatographic data acquisition, automatic or manual setting of integration parameters, up to 5 quantitative methods, baseline deduction, report preparation, and other functions.
