lc-ms is nothing but hplc/uplc attached to a mass spectrometer by which the seperation as well as identification on the basis of m/z is possible.Its use in cro and pharmaceuticals is much in new molecule development.

Answer / anji

lc-ms is lc is combined with mass spectroscopy by inter
face.in this separation as well as identification of
molecule by their m/z. it is mostly used in cro industry
because it detect new molecles. inter face used as to remove
solvents and buffers from out let of lc.

Answer / chandu 4m apex

lc for seperation of the analyte, ms for to confirm analyte by their molecular weight.

Answer / shivaji musmade

Lcms is combination of the liquid chromatography& mass spectroscopy its use in cro for identification of unknown molecule by its m/z ratio & also used in reaction monitoring analysis to confirm how much product form and how much unreacted is remaining.
