Abstract

A system for real-time fluorescent determination of trace elements comprising means for moving a plurality of samples (14) having at least one trace element along a sample path; means (22) for generating a plurality of incident radiation pulses of different wavelength; means for illuminating at least a respective one of the samples with at least a respective one of the radiation pulses during the movement of the samples, the radiation pulse having a suitable range of fluorescence radiation wavelengths; means (22) for detecting the resultant fluorescence emitted from each of the samples; and first control means (24) in communication with the moving means and the incident radiation generating means for synchronizing the means for illuminating each of the samples with the moving means.
