Fundamental ICP-MS class room course
1 Day Course

This one-day course introduces delegates to the fundamental concepts and principles associated with ICP-MS. Topics covered allow the ICP-MS user to gain a useful insight into the operating principles of the instrument.

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

A comprehensive one day course designed to increase expertise and optimise results for all users of ICP-MS.

Understanding sample introduction and optimisation of instrument performance are important subject areas within this one-day course. Interactive Training sessions and tutorial exercises are used to reinforce key learning points.

Who is this course for

This course is ideally tailored towards either the experienced user who is looking for a refresher course, or towards a new user who is looking for an introduction to the analytical technique.

Previous knowledge

Background knowledge of ICP-OES or Mass Spectrometry may be useful but not necessary, as all the essentials are covered in the course. Previous experience using ICP-MS equipment can be beneficial.

  • How ICP-MS can be used for the analysis of ultra-trace metal elements (0.0005-100ppb)
  • Application of ICP-MS to non-metallic elements (e.g. S, P)

Quadrupole Mass Analysers- Mass Gain and Offset

Instrumentally, the DC voltage (U) and RF voltage (V), are altered according to a linear relationship which is often referred to as the ‘SCAN’ line or ‘SCAN’ function. The mode of operation for a mass analyser in which the voltages U and V are ramped linearly is often referred to as SCAN mode.

The slope of the SCAN function (i.e. the rate of change of U against V) is often referred as the quadrupole GAIN. The intersection of the scan line with the U axis (i.e. the magnitude of the initial DC voltage applied) is the quadrupole OFFSET.

The stability diagrams for THREE ions of mass m 1, m 2 and m 3 are shown opposite and it can be seen that very often the stability regions of ions overlap. To ensure that ions of only one selected m/z value are transmitted, the parameters U, V (at certain selected ω) must be chosen so that the line representing U/V (or a/q) passes close to the apex of region A but still lies within the stable region. If the slope of the line is increased so that it misses the apex of the stability region, no ions of that m/z value will be transmitted. For a given quadrupole assembly, ro and ω are fixed and it is electronically more straightforward to manipulate the voltages U and V. Therefore to transmit ions of subsequently higher unit mass, the voltages U and V are increased (m/z is inversely proportional to both a and q), whilst the ratio U/V (or a/q) is fixed (i.e. the slope of the line is constant ).
