Features:
● Self-diagnostic function:
(1) Core tests; (2) Automatic tests; (3) Extended tests; (4) Basic tests;
Monitor the status of GC continuously. Once finding faults, it will display the information, show the wrong zone and the settling method.
● Self-protective function:
(1) Overrun temperature protection; (2) Short circuit hint; (3) TCD filament protection; (4) FID flameout hint;
(5) PFD exposed-light protection; (6) Keyboard locked function utilizing password; more kinds of protect function ensured GC's normally running.
● Simple operation, powerful automation:
(1) All parameters can be entered through keyboard with prompt function;
(2) Storing 4 complete chromatography analysis methods which can be activated automatically;
(3) Can be connected with Autosampler;
(4) Parameters can be modified instantly while the GC is running;
(5) Chromatography analysis method can be activated for 99 times repeatedly at one time. It's especially suitable for in nobody guarding situation.
● More choices of injectors:
(1) On-Column Injector for Packed Column; (2) Flash Vaporization Injector for Packed Column
(3) Automatic or manual gas inject valve; (4) Headspace sampler; (5) Thermal desorption system
(6) Split/Splitless Capillary Injector; Three Injectors or two Split/Splitless Capillary Injectors can be fixed on GC.
● More choices of detectors:
(1) TCD; (2) FID; (3) ECD; (4)FPD; (5) TSD
Maximum of two TCD installed or three different kind of detectors.
● Reactor: (1) Internal; (2) External
● Time programming of Detectors:
Each of detectors has 5-ramp programmable time control, output-signal, attenuation range, and polarity can be changed automatically.
● Time programming of external events:
Provide 4 external events with 20-ramp programmable time control; the optional GC relays may be used to automate valves, to operate split/splitless capillary injectors, or drive auxiliary functions, or switch signal between detectors A and detector B during a run.
