Trace Element Analysis

Extreme care is necessary in trace element analysis. Before use, polythene containers for storing sample and standard solutions should be washed successively with:

• H2O, triply deionized or distilled (Adriano et al., 1971).

Earth dust must be rigorously excluded and gently washed from foliage if necessary.

Solutions and leachates for analysis must be particle free, and should therefore be centrifuged in polypropylene tubes and not filtered unless this is specified in the methodology.
