LCMS is a powerful analytical technique used for identification of both unknown and known compounds Mass identification as well as to elucidate the structure and chemical properties of different molecules.

LCMS/MS the determination of both molecular ion and fragment ions permits more accurate identification analysis than identification using molecular ion alone. The fragmentation voltage can be controlled to encourage more stable molecules to fragment increasing the number of compounds which can be identified by LC-MS/MS.
