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
The extract was filtered and the filtrate diluted with an equal volume of water. 50 ml strong solution of lead subacetate was added and the mixture centrifuged after 5 minutes. Excess lead was precipitated with 10% disodium hydrogen phosphate and the mixture again centrifuged. The supernatant was su
