LC-MS
Liquid Chromatography Mass Spectrometry (LC-MS):
LC is the separation technique of choice for larger and non-volatile molecules such as proteins and complex peptides. When combined with MS, LC-MS offers broad sample coverage because different column chemistries, such as reversed phase liquid chromatography, can be used.
Thermo has range of LC-MS models which ranges from basic one to single Quadrupole, Triple Quadrupole and Ion Trap LC-MS.
