University Teaching of Mass Spectrometry as a Key Practical Technique
within the Context of a Fully-Integrated, Spiral Curriculum.
Abstract
Rationale: Mass spectrometry (MS) is introduced to high school
students in the UK in many pre-university course syllabi. As such, we
have identified the use of MS as a key technique that should be taught
practically to undergraduates from the outset of their studies. This
mini‑review describes how we introduce and develop students’ use of MS
throughout our three‑year undergraduate spiral curriculum practical
program, using atmospheric pressure chemical ionisation MS (APCI/MS).
Methods: We have used an Advion Expression L
spectrometer, fitted with an atmospheric solids analysis probe or a
Plate Express TLC sampler for sample introduction. Results: We
have successfully demonstrated the use of APCI-MS in a range of
practicals and experiments covering organic and organometallic
chemistries, with large cohorts of students gaining hands‑on
instrumental experience in authentic research settings.
Conclusions: APCI-MS has proven to be an easy-to-use and
valuable addition to our undergraduate practical course. The robustness
of the spectrometer enables routine use by large cohorts of students
with minimal supervision, and routine maintenance can be carried out by
non-specialist technicians. Students can readily process and interpret
results for a series of routine analyses, as well as demonstrate uses in
problem-solving exercises.
