Technique Selection

From WRC

 

Where time permits, WRC and 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.

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

Instrument Media Typical Analytes Typical Detection Limits Sample Required Comments
ICP-AES Water;
Rock/ soil/ biological media digests
Na,K,Ca,Mg, Ba,Sr, Fe, Mn, As, P,S, Si, Cu, Zn, Pb 0.1 – 1mg/L 10mL in 2% HNO3
Maximum TDS 1%*
Workhorse for determining major cationic components in waters or digests
