Valve Oven
Stainless steel and Silcosleeves liners are shown above with a mega-bore column adapter.
The Heated Split/Splitless injector is insulated to help maintain its temperature independently of the column oven temperature.

The heated split/splitless injector permits the use of narrow-bore capillary columns (0.32 mm I.D. and smaller) in split or splitless modes. Capillary columns with 0.53 mm I.D. and 1/8″ packed columns can be used in split, splitless, or on-column modes. The injector temperature is adjustable utilizing a precision needle valve and can be turned ON/OFF with a timed event from the PeakSimple data system. One silcosleeve liner and one unbreakable stainless steel liner are supplied as standard equipment with the injector.

The split flow is adjustable by a precision needle valve on the front of the GC valve oven. The valve oven pictured at left is on a GC that is also equipped with a gas sampling valve, and the sample inlet and outlet are also on the front of the valve oven.
