A Simple Apparatus for Thin-layer Chromatography.
Thin-layer chromatography was introduced by Stahl (1956) and has advantages over paper chromatography in speed, resolution, and smaller sample size. Also, the physical nature of the thin layer allows its treatment, where necessary, with strong acids and alkalis. It has been found possible to construct a satisfactory, cheap, and simple apparatus for the preparation of thin layers on glass carrie...
متن کاملPhosphorus determination in phosphoglycerides from thin-layer chromatograms ARTHUR
Phosphoglyceride phosphorus is readily determined directly on silica gel removed from thin-layer chromatograms, without elution, by a nondigestive procedure with a sulfuric-periodic acid reagent. The method is specific for hydrolyzable phosphoglyceride containing two acid-hydrolyzable groups. Cariolipin reacts only partially, while sphingomyelin, diether lecithin, and phosphonate cephalin fail ...
متن کاملTime resolved chromatograms in ultra-thin layer chromatography.
Ultrathin-layer chromatography (UTLC) is a recently developed analytical method intended for compact, rapid separations of nanolitre analyte volumes. Optimizing this method's performance requires new measurement techniques compatible with the millimetre length scales and rapid separation dynamics observed in UTLC. We have designed, implemented and characterized a measurement system which record...
متن کاملSpray detection of phospholipids on thin-layer chromatograms.
A new spray reagent with copper, ammonium molybdate, and sulphuric acid for the detection of phospholipids on thin-layer chromatograms is described. The specificity and sensitivity of the spray reagent is also shown.
