 SP-3400 Gas Chromatograph, made according to international standars, its technical feature and index are in the world high level. The key components are imported from world famous suppliers. It is widely used for petrol-chemistry, environmental protection, epidemic prevention, pharmacology, scientific research, etc.
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'll display the information and show the wrong zone and the setting 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 analisys 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 Vaporizator 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 injectorcan be fixed on GC.
More choices of detectors:
1. TCD, 2. FID, 3. ECD, 4. FPD, 5. TSD Maximum of two TCD's 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/splitles 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.
