Abstract [en]

The task of analyzing complex samples has always been the challenge for the analytical sciences. Today more effort is put into characterizing a greater number of sample constituents, at lower levels and with higher speed and accuracy, all in one analytical run. Present challenges consist of, for example, the analysis of samples with biological/environmental origin measuring as many constituents in the sample as possible. By hyphenating chromatography (GC or (UP)LC) with mass spectrometry (MS) several hundreds of different molecules can be screened in one analysis - now we are faced with the problem of analyzing the large amounts of generated data, trying to extract the relevant information. This is where the fields of chemometrics and data processing, and hyphenated chromatography are successfully married. Here we outline some of the data requirements and new algorithms making exploratory analytical chemistry possible.
