摘要:
AbstractA cold on‐column injection system for capillary gas chromatography (GC) applications was constructed. It was based upon a conventional split/splitless capillary GC inlet, which in turn was a modification of a conventional packed GC column inlet. The heart of the laboratory constructed cold on‐column inlet design was a disposable pyrex micro‐sampling pipet, which functioned as a needle guide for sample injection. The sample was injected through a traditional GC septum. Construction of the injection system is described and applications are illustrated by separations of a variety of complex mix

摘要:
AbstractHigh performance thin‐layer chromatography (HPTLC) was used to determine 12 metabolites of the tryptophan‐NAD pathway in rat urine. The method of separation described in the previous report was improved. The metabolites were separated on the cellulose plate by using five multiple developments with four solvent systems. The plate was scanned by the TLC scanner at 254 nm and the amounts of the metabolites were calculated by comparing peak areas of the scanning curves obtained for the urine sample and for the authentic standards. This procedure can be used as a semiquantitative determination method for the metabolites in biological flu

摘要:
AbstractSequential centrifugal layer chromatography (SCLC), a new preparative planar separation technique, combines the advantages of preparative centrifugal layer chromatography (CLC) and analytical, horizontal, anticircular, and sequential thin‐layer chromatography (TLC). In this on‐line preparative method, solvent delivery is locally and temporally variable, which means that the mobile phase can be brought onto the plate at any desired place.The SCLC apparatus operates in two modes: circular, with the help of centrifugal force in an inclined position, and anticircular, by means of capillary action in a horizontal position. These two operation modes can be combined and repeated as often as required, hence the separation space becomes practically unlimited. In this way the capacity and separation performance is significantly increased.In the present paper the apparatus and the method are described and some practical aspects are mentio
