The Atmospheric Pressure Interface (API) is the core element to the course with the principles of operation, limitations and applicability fully explored.
The course covers ion suppression, the use of Electrospray or APCI and MS-MS data acquisition modes. Optimisation of interface and mass filter settings and how to best utilise reduced dimension LC to speed up sample throughput will be discussed.
All popular interface types and mass analysing equipment (quadrupole, TOF, ion trap, etc.) are comprehensively covered.
Who is this course for
Users of LC-MS and LC-MS-MS equipment, or anyone interested in learning the analytical capabilities afforded by this type of instrument.
No previous knowledge of mass spectrometry is necessary, but an understanding of the fundamentals of liquid chromatography is beneficial.
