Thin-layer chromatography with multiple one-dimensional elution was used to determine the molecular-weight distribution of polyethylene glycols of the general formula HO(CH2CHz0)nH after conversion into their dichloro derivatives. The adsorbent was silica gel, the developer was based on a mixture of

A selective and sensitive capillary column gas-liquid chromatographic procedure has been developed for the simultaneous determination of isosorbide dinitrate (ISDN) and its mononitrate metabolites in rabbit blood and tissue homogenates. The method has a limit of detection of O.lng ml-l for ISDN, l n
