CAPILLARY LIQUID CHROMATOGRAPHY: GREEN ANALYTICAL TECHNIQUE AND SOME SIMPLE WAYS OF ITS REALIZATION

Popis výsledku v původním jazyce

Reduction of organic solvents consumption as well as replacement of some solvents with less harmful alternatives is required by the green chemistry philosophy. High performance liquid chromatography (HPLC) is a widely used tool in analytical chemistry. Hence, in the green analytical chemistry, a solvent consumption of new liquid chromatography methods should be reduced substantially. Realization of the HPLC with capillary columns thus represents a straightforward option of the significant solvent consumption decrease. Namely, N-fold reduction of the internal column diameter leads to N2-fold reduction of the column cross section and the corresponding flow rate as well. In this presentation, some equations related to the column diameter reduction will behighlighted and resulting demands on the sample injection volume and the photometric detection will be discussed. Acetonitrile is a common organic modifier in HPLC mobile phases due to UV transparency, low viscosity and low reactivity. H
