The Varian 3900 GC with CP-8410 Autoinjector is an all electronic, single channel gas chromatograph. The keypad relies on icons to identify the actions of the keys on the keypad. The icons are color coded to allow quick identification of what will happen when a key is pushed.
The CP-8410 is an AutoInjector based on the CP-8400; it has a manually positioned tray and can accommodate up to 10, 6, and 5 each of 2 mL, 5 mL and 10 mL vials, respectively. Both the AutoSampler and AutoInjector can inject into up to two injectors; the injection may be made into either one or the other of the injectors or into both (either from the same vial or from adjacent vials) during the same run.
