Tandem mass spectrometry (MS/MS) is widely employed for the analysis of complex proteomic samples. The coupling of chromatography with MS is a well developed chemical analysis strategy dating back from the 1950s. The power of chromatography 9 comes from its ability to separate a mixture of compounds, or "analytes", and 10 determine their respective identity (chemical structure) and concentration. A range of qualitative N-glycan standards labeled with IPC are available to assess HILIC/FLD/MS retention times and masses. What is Chromatography? Liquid chromatography-mass spectrometry (LC-MS) Combines the physical separation capabilities of LC with the mass analysis capabilities of MS Thermal analysis Analyzes materials according to the way they change with tem-perature. I, The IUPAC Definition of Chromatography "Chromatography is a physical method of separation, in which the components to be separated are distributed between two phases, one of which is hpl whilst the other moves in a definite direction". Feel free to suggest additional resources in the comments! The solution to this problem and subsequent viability of LC-MS earned John Fenn the Nobel Prize.
