Abstract
An interlaboratory survey, involving 22 participants, showed generally good intralaboratory precision, but poorer interlaboratory correlation. The most common procedure used mineral acid digestion followed by flame atomic absorption spectrometry. It was found that data obtained by different laboratories can be compared provided that (i)similar analytical procedures are followed and (ii) regular interlaboratory comparison studies take place in order to ensure that systematic interlaboratory differences will not occur.
