Qualitative methods are frequently used for screening. In some applications, the resulting positive samples are subsequently analyzed by a suitable quantitative confirmatory method, so it is important that the qualitative assay provides reliable resu

Uncertainty is a performance characteristic that should be estimated in both quantitative and qualitative results in order to improve knowledge of their reliability. Contrary to quantitative results, uncertainty in qualitative analysis cannot be expr

We simultaneously determined carbendazim, fuberidazole and thiabendazole by excitation–emission matrix (EEM) fluorescence in combination with parallel factor analysis (PARAFAC). Three-way deconvolution provided the pure analyte spectra from which w

A procedure to calculate the uncertainty associated to a binary response, of the type yes/no, originated from an instrumental screening system, is described. Useful equations have been developed based on statistical intervals, and their validation we
