Cation Analysis by Thin - Layer Chromatography and Reflectance Spectroscopy
A procedure whereby reflectance spectroscopy can be employed for the analysis of substances resQlved on thinlayer plates was developed with the use of metal cation mixtures that had been separated on cellulose plates. A rapid method was devised whereby fourteen cations were separated and identified ~~ by their reflectance spectra after chromogenesis with a mixture of dithizone and 8-hydroxyquin...
متن کاملLayer-Resolved Evolution of Organic Thin Films Monitored by Photoelectron Emission Microscopy and Optical Reflectance Spectroscopy
Photoelectron emission microscopy (PEEM) and differential (optical) reflectance spectroscopy (DRS) have proven independently to be versatile analytical tools for monitoring the evolution of organic thin films during growth. In this paper, we present the first experiment in which both techniques have been applied simultaneously and synchronously. We illustrate how the combined PEEM and DRS resul...
متن کاملDetermination of carotenes by thin-layer chromatography.
The carotenoids of yellow, red and tangerine tomato fruits were separated and identified by thin-layer chromatography (TLC). β-carotene is extracted with a mixture content hexan and acetone. The various systems of adsorbents and solvents for TLC of carote and tomato carotenes were examined, and it was revealed that the most suitable TLC system for separation and identification was silica gel pl...
متن کاملIdentification of Barbiturates by Thin-layer Chromatography.
in cases of overdose and identification of the actual barbiturate concerned may be impossible because of the closely similar Rf values of this group. Jackson (1960) described treatment with hot sulphuric acid before paper chromatography to distinguish between barbiturates of similar chromatographic mobility. The inert nature of the silica gel supporting medium used in thin-layer separations ena...
