Methods of Analysis

In this course, Dr Giorgio Chianello (QMUL) introduces to us the methods of analysis that chemists use in the laboratory to identify atoms, molecules and compounds. We begin by: (i) discussing melting point analysis; and (ii) chromatography techniques; before (iii) introducing the term “spectroscopy” and the information we can gather from IR spectroscopy; followed by (iv) UV/Vis spectroscopy, and distinguishing their differences; then (v) looking at mass spectrometry, how it works and sample spectra; and finally (vi) more advanced methods of analysis you may encounter in future studies. Note: NMR spectroscopy is not discussed here since it is covered in another lecture in more depth.

Melting Point Analysis

In the first mini-lecture, we discuss melting point analysis. Many solids in chemistry - or indeed in your kitchen - are white and can look identical. Melting point analysis provides a safe way to determine the compound you have, since the experimental melting point you find can be compared against databases of melting points you can find in textbooks. In this lecture we are shown what a melting point apparatus looks like, as well as examples of compounds on which the method can be used.
