Part II. Introduction to LC-MS :
Led by an Application Specialist from SCIEX this module will introduce and develop new practitioners by delivering an understanding of basic mechanisms associated with LC-MS/MS. As well as discussing mass spectrometry fundamentals, the material will then go on to examine the most commonly applied LC-MS techniques and the principles behind them:
- Atmospheric Pressure Ionisation theory, techniques and methods:
- Desolvation
- Electrospray Ionisation (ESI)
- Atmospheric Chemical Ionisation (APCI)
- Mass Analysis
- The importance of calibration, and the differences between nominal mass, accurate mass and mass resolution
- Mass Analysers
- Quadrupole – benefits, limitations and general usage
- Time of Flight – benefits, limitations and general usage
- Data analysis
- Quantitation
- Application of targeted techniques eg MRM to data acquisition and processing
- Qualitative approaches to identification
- Application of discovery techniques eg scanning, information dependent acquisition, library searching
