## Abstract Capillary columns of 0.3β0.5 mm i.d. packed with 3β to 30βΞΌm silicaβbased stationary phases for liquid chromatography were used for gas chromatographic separation of hydrocarbons. Column efficiencies were evaluated for various commercially available packing material. The best column eff
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
