Course information
LC-MS Applications, Troubleshooting & Method Development
Design robust, high-sensitivity LC-MS analytical methods and streamline real-world quantitative workflows.
AUDIENCE: ANALYTICAL CHEMISTS & METHOD DEVELOPERS · LEVEL: ADVANCED · TRAINING TYPE: LIVE ONLINE INTERACTIVE SESSION
Developing reliable LC-MS methods requires balancing liquid chromatography parameters (column selectivity, mobile phase pH, gradient profiles) with mass spectrometry settings (source temperature, desolvation gas flows, voltage settings, MRM/SIM transitions). A failure to optimize both sides leads to variable ionization, poor sensitivity, and irreproducible quantitative data.
This intensive course delivers a systematic framework to build, refine, and validate LC-MS assays across diverse target analytes and complex sample matrices.
Systematic alignment of mobile phase volatile additives and source ionization voltages eliminates suppression and unlocks trace-level detection limits.
