A new principle and method have been developed for producing a high-efficiency WCOT column by forming a polyimide capillary tube of l-5 pm wall thickness inside a supporting glass capillary (tube-in-tube system). This polyimide layer is chemically resistant, heat-proof (up to 450Β°C) and mechanically
Capillary columns are widely used in gas chromatography (GC) because of their high resolving capacity. Split, splitless and on-column techniques are used to introduce the sample. A conventional vaporizing GC injector can easily be converted into a split/ splitless injector. However, it cannot be us
