The mass spectrometer . . .

Includes an explanation of how the mass spectrometer works and how it can be used both to find relative atomic masses of elements and to help to identify organic compounds.

Infra-red spectra . . .

Explains how infra-red spectra can be used to identify particular groups in an organic compound, or even to identify the whole compound.

Nuclear magnetic resonance (NMR) spectra . . .

Explains how both C-13 NMR spectra and low and high resolution proton NMR spectra can be used to help to work out the structures of organic compounds.

UV-visible absorption spectra . . .

Explains the origin of UV-visible absorption spectra, how they are measured, and how they can be used in the analysis of organic compounds.

Chromatography . . .

An introduction to various forms of chromatography: thin layer, column, high performance liquid (HPLC), gas-liquid and paper.
