24th Molecules Webinar

Chromatography—the Ultimate Tool: Analysis and Sample Preparation

Since its introduction by the Russian botanist Mikhail Semyonovich Tsvet, chromatography has been the most powerful analytical tool in Analytical Chemistry. Separation, qualitative analysis, and quantitative analysis can be achieved by choosing the right conditions. Thus, numerous gas chromatographic, liquid chromatographic, and supercritical fluid chromatographic methods have been developed and applied for most types of samples and most kinds of analytes. Not to mention that older varieties like paper chromatography and thin-layer chromatography were pioneer analytical techniques in many laboratories. Especially when hyphenated to spectrometric techniques, chromatography also allows the identification of separated analytes in a single run. Highly sophisticated equipment can answer all analytical problems very quickly. Chromatographers cooperate with many scientific fields and give their lights to medical doctors, veterinarians, food scientists, biologists, dentists, archaeologists, etc. The choice of two-dimensional approaches can expand the power of chromatographic techniques either in heart-cut or comprehensive modes.
In this webinar, experts in the field will present the state of the art in chromatography as a tool in chemical analysis and green sample preparation.
