A method for quantifying at least one microorganism group via at least one mass spectrometry analysis is described. The method includes at least one separation and fragmentation step. The method moreover includes a step that involves measuring the amount of at least one representative peptide or at least one protein representing the microorganism group. The at least one representative peptide or the at least one protein is obtained after the at least one separation and fragmentation step and serves as a quantification marker(s). The amount of the quantification marker(s) is directly correlatable to the amount of the at least one microorganism group.

The present invention concerns the preparation of solutions, particularly for implementing analytical methods, in particular by spectrometry, particularly for producing standard solutions which are useful, for example, for calibrating spectrometers or for implementing diagnostic methods. It allows the implementation of an easy process for preparing such standard solutions.
