Beijing Beifen-Ruili Analytical Instrument (Group) Co.,Ltd. 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; 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. ♦ 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 set automatically. ♦ Time programming of external events: Providing 4 external events with 20-ramp programmable time control. The optional GC relays may be used to automate valves, operate split/ splitless capillary injectors, drive auxiliary devices, or switch signals between detector A and detector B in a run. ♦ Many kind of special-purpose GC can be provided according to user’s request.
