APPLICATIONS

SP-3400 Gas Chromatograph, made according to international standards, 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

Ÿ 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.

Ÿ 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.

Ÿ 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.

Ÿ 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.

Ÿ 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.

Ÿ Reactor

1) Internal

2) external

Ÿ Time programming of detectors

Each of detectors has 5-ramp programmable time control. Output-signal, attenuation range, and polarity can be set automatically.

Ÿ 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.

Ÿ Many kind of special-purpose GC can be provided according to user’s request.
