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'll display the information and 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 locking with password; etc., ensuring normal running.
Simple operation, powerful automation: 1) All parameters can be entered through keyboard with prompt function; 2) 4 sets of complete chromatography analysis methods can be stored and recalled automatically; 3) An autosampler can be connected; 4) Parameters can be modified instantly while the GC is running; 5) Chromatography analysis method can be activated for 99 times repeatedly at the same time. It's especially suitable for unattended operation.
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 TCDs or three different kinds of detectors can be installed.
