Abstract

A procedure for the analysis of a sample is disclosed, where the sample includes at least one nucleic acid molecule having at least one nucleic acid sequence. In at least one embodiment, the procedure includes making available a comparison molecule of known concentration having a known comparison sequence, where the comparison sequence has a defined mass difference in comparison to a reference sequence of the nucleic acid sequence; cleaving the nucleic acid sequence to give fragments of the nucleic acid sequence and the comparison sequence to give fragments of the comparison sequence, determining a mass spectrum of a mixture of the fragments of the nucleic acid sequence and of the comparison sequence by means of mass spectrometry, determining a comparison spectrum of the fragments of the comparison sequence by means of mass spectrometry, determination of the concentration of the nucleic acid sequence from the mass spectrum and the comparison spectrum and determining still unknown sequence variations of the nucleic acid sequence in comparison to the reference sequence from the mass spectrum and a reference spectrum of the reference sequence.
