Description
Finnigan MAT LCQ Mass Spectrometer System analyte separation via liquid chromatography, coupled with electrospray ionization (ESI) quadrupole ion-trap mass spectrometry. Its capabilities include full MS with Selected Ion Monitoring (SIM), MS/MS with Selected Reaction Monitoring (SRM), CRM, full scan and zoom scan. Electrospray ionization (ESI) broadens the list of compounds suitable for mass analysis by enabling ionization of compounds with high molecular weight and very low volatility. The LCQ is very versatile and while able to analyze smaller molecules as well, the instrument is best suited for analysis of proteins, peptides, and other large non-volatile polar molecules, and has the advantage of automated MSn (n = 1 to 10) scanning of fragment peaks for more detailed molecular structure information.
