| Abstract: | Thermofractography – A Novel Microanalytical Method for the Rapid Analysis of Lipid Mixtures New possibilities now exist for the rapid analysis of lipid mixtures in micro-scale through fractionated carrier gas distillation in direct coupling with the thin-layer chromatography (= Thermofractography). To begin with, the behaviour of pure substances in the temperature gradient 50°–450°C was investigated. It was observed that numerous compounds, which are otherwise separable only via vacuum distillation, pass over with the carrier gas at normal pressure. In this connection, the thermolysis of such compounds was also investigated. Practical cases of application, e. g. fats and oils, mayonnaise, dairy products, chocolate base are given and other possibilities are discussed. |
