Letter: Analyzing for organic mercurials by gas chromatography.
Dear Sir: A recent review by Dr. Mushak (1) discusses several of the procedures used to analyze for organic mercurials by gas chromatography. He points out that there are several problems associated with these procedures, including halide exchange and decomposition on-column, and difficulty in unambiguously identifying the "peak" as being due to the compound expected. We feel that the technical...
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...

متن کاملThin-Layer (Planar) Chromatography
Synthetic dyes comprise a large group of organic, organic salt and organometallic compounds which number in the thousands. Most individual dyes are assigned colour index (CI) numbers which helps to identify structure and properties as well as identity where a series of names have been used by the manufacturers for the same dye. Pigments are also listed and can be either organic or inorganic in ...
