Technique selection

Where time permits, MAGU staff will provide advice and help you select the most suitable available technique for the analytical work you may require. We strongly recommend, however, that you avail yourself of the relevant training programmes available within the School and other Schools with the Faculty of Engineering and Physical Sciences.

Typical applications

The table below shows typical applications of major techniques available – capabilities however do extend beyond the commonly analysed analyes and media listed.

Note: TDS = total dissolved solids.
