LC-MS training for the Chromatographer class room course
1 Day Course | LC-MS Level 1

We have distilled critical knowledge of Liquid Chromatography and Mass Spectrometry applications and instrumentation into this exciting and interactive short course. You will learn the absolute essentials of the technique and, using our unique multi-media examples and tutorial exercises, you will implement new knowledge and ideas immediately.

  • We limit numbers to 20 per course so that each delegate gets the opportunity to ask questions and fully participate in tutorial exercises
  • When delivered on-site we can design the course material to suit your specific training needs
  • Customisable written assessments are available if required

download course pdfThe 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.

Previous knowledge
No previous knowledge of mass spectrometry is necessary, but an understanding of the fundamentals of liquid chromatography is beneficial.

What you will learn

  • How modern API designs work and which one best fits your LC  and application requirements
  • How ions are produced and how to optimise LC mobile phase and interface parameters to achieve highest sensitivity, accuracy  and reproducibility
  • The anatomy and working principles of quadrupoles, ion traps, magnetic sector, time-of-flight detectors and more

Instrument Fundamentals

The mass spectrometer is an instrument designed to separate gas phase ions according to their m/z (mass to charge ratio) value.

Mass spectrometry involves the separation of charged species which are produced by a variety of ionisation methods in LC-MS. These include:

  • Electrospray Ionisation (EI)
  • Atmospheric Pressure Chemical Ionisation (APCI)
  • Atmospheric Pressure Photo Ionisation (APPI)

In all cases the charged species are produced as gas phase ions under atmospheric pressure conditions.

The separation of the gas phase ions is achieved within the mass spectrometer using electrical and/or magnetic fields to differentiate and separate ions.

In addition to the mass analyser, the mass spectrometer also includes an atmospheric ionisation chamber, and a detector. The mass analyzer and detector systems are held within a vacuum chamber.
