Title: Quantitative determn. of thin layer chromatography fractions - by processing various materials pyrolysed by microwave or laser
Inventor: ADAM OLAF DR
IPC: G01N27/447
Filed: 1989-07-03
Abstract: To add quantitative determn. to the qualitative sepn. of fractions by a thin layer chromatograph, these are individually converted into volatile hydrocarbons by a forcussed. laser or microwave beam. A stream of carrier N2 takes these hydrocarbons in succession to a copper oven which converts them to CO2. In a nickel oven the CO2 is then reduced by H2 to form methane, and quantitative analysis of the methane by a flame ioenisation detector permits calculation of the initial amt. of sample, e.g. lipids. A suitable focussed microwave is in the frequency range 10-15 gigaHz.. and a focussed laser beam would have a thickness of 0.1 mm and width of 7 mm. ADVANTAGE - Fractions are mroe sharply differentiated and gas leakage prevented
