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 for non-fluorinated compounds!
Determination of free amino acids in various liquids
Determination of the amino acid composition, amino sugars, and content of peptides and proteins
Quality control of peptides and proteins by amino acid analysis
Sequence determination of peptides by MS/MS
