The quality of an analysis can be described by accuracy, trueness, precision, resolution and criteria for deciding whether or not the presence of an analyte has been proved. There is a need to define the degree of (un)certainty of qualitative methods

In order to create a system for qualitative analysis, in which well defined limits of ambiguity can be set, criteria have been formulated for application to the identification method(s) used. Criteria are presented for separation techniques (thin-lay
