Gas Chromatography (GC) Interface Supplies for ICP-MS
Argon make-up gas supplied by the ICP-MS is preheated via a stainless steel heat exchanger inside the GC oven before being added to the GC column effluent at the head of the transfer line. In this way, the sample is maintained at constant high temperature from the end of the chromatographic column in the GC oven to the tip of the ICP injector.
