Description:
An inductively coupled plasma, multielement atomic emission spectrometric analysis system has been evaluated with respect to the Environmental Protection Agency's need for a rapid method for determination of trace elemental concentrations in water. Data are presented on detection limits, curve fits and reproducibility of analytical curves, photomultiplier performance, dynamic range, reproducibility of analytical results, and stray light properties of the instrument. The instrument as a whole performed well, but stray light arising from calcium and magnesium in typical hard waters caused significant errors at low concentration levels for a number of critical elements. Suggestions for reduction of the stray light and for empirical correction of its effects are discussed.
