title: A factor analysis approach to optimized line selection in inductively coupled plasma atomic-emission spectrometry.
abstract: The best analytical line for determination of a specified analyte is selected from a set of lines on the basis of the least interference in a particular sample matrix, by several cycles of mathematical analysis. Unsuitable lines are rejected in the first few cycles, the best lines being retained until last. A multivariate analysis after each cycle provides an updated estimate of the analyte concentration. This process is performed without reference to spectral tables.
