MSn respectively HPLC-MSⁿ can be offered for peptide sequencing, determination of molecular weight of peptides and identification of side products. If necessary separation can be performed using HPLC on suitable columns. Peaks are detected by diode array detector and transferred online into mass spectrometer. After electro spray ionization (ESI) the components are identified by MSⁿ.

Results: Molecular weight y,
b and a-type fragments which are to determine.
