ECG-510

Model: ECG-510

Features:

(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. (2)
(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. (2)
All parameters can be entered through keyboard with prompt function; (2)
Automatic or manual gas inject valve; (4) Headspace sampler; (5) Thermal desorption system (2)
Can be connected with Autosampler; (2)
Chromatography analysis method can be activated for 99 times repeatedly at one time. It's especially suitable for in nobody guarding situation. (2)
Each of detectors has 5-ramp programmable time control, output-signal, attenuation range, and polarity can be changed automatically. (2)
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.
On-Column Injector for Packed Column; (2) Flash Vaporization Injector for Packed Column (2)
Parameters can be modified instantly while the GC is running; (2)
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. (2)
Reactor: (1) Internal; (2) External (2)
SP-3400 series Gas Chromatographs use the newest technique introduced from Varian Associates in the United States. With the international standard production, its technical feature and index are in the high level of the world. The gas valves and the key component of detectors are imports from Amercia. Widely used for petrol-chemistry, environment protection, epidemic prevention, pharmacology, scientific research, etc.
Split/Splitless Capillary Injector; Three Injectors or two Split/Splitless Capillary Injectors can be fixed on GC. (2)
Storing 4 complete chromatography analysis methods which can be activated automatically; (2)
