(Nano-) Electrospray Ionisation Mass Spectrometry (ESI-MS)
Electron Ionization Mass Spectrometry (EI-MS)
Accurate Mass Determination
Determination of the Elemental Composition
Tandem Mass Spectrometry (MS/MS)
This method is used for organic samples that cannot be analysed by ESI-MS.
The percentage of carbon, hydrogen, nitrogen (and sulfur) are determined by combustion of the material followed by gaschromatography of the produced gases.
At least 5-6 mg of material are needed for an analysis in triplicate.
Standard method is CHN
CHNS only on request and for non-fluorinated compounds! Minimum sample number of 10.
Determination of free amino acids in various liquids
Bound amino acids in biological samples
Amino acid composition of peptides and proteins
Quality control of peptides and proteins by amino acid analysis
Sequence determination of peptides by MS/MS
