Miniaturized chromatographic method, related uses, and automated multidimensional solid-phase extraction chromatographic system

Abstract

One objective of the present invention is to provide a miniaturized chromatographic method for the selective extraction of polar compounds from crude oils, which is faster and more economical in terms of sample consumption, solvent volume, and waste generation, without compromising the chemical signature of the sample. Specifically, the method employed was solid-phase extraction (SPE), in online and offline modes, for the prospecting of polar compounds from crude oils, together with H-MPLC, in order to support a greater understanding of petroleum systems through the development of faster, more selective, economical, and environmentally more sustainable analytical and chromatographic methods. Furthermore, the invention also provides to describe an automated multidimensional solid-phase extraction (SPE) chromatographic system, which is applied in said method, as well as to describe some uses of said method.
