Chapter 1 Introduction Valve Oven Overview Options The type of valve enclosure can be selected among three different options depending on the analytical requirements. 1. TRACE GC Ultra Valve Oven It provides an additional isothermal heated zone to accomodate valves and columns. It consists of an inner heated enclosure and an external unheated area. The former is designed to house up to four heated valves, restrictors and 1/8” OD packed columns. The latter houses up to two valves and pressur

Chapter 1 Valve Oven Overview Installation and Power Requirements When up to two Valco Purged valves are required (e.g. applications with Pulsed Discharge Detector), this option has to be selected for their housing. For more informations, refer to Valve Oven Components. NOTE When any Valve box (heated or unheated) is configured with valves, these are factory tested to verify actuation but are NOT plumbed. Plumbing can be performed upon availability of plumbing diagrams. Materials needed: Sho
