Discrimination of complex substances with Laser-Induced Breakdown Spectroscopy (original) (raw)

2009

Abstract

One of the most pressing applications for LIBS is the detection of toxic metals in various matrices. For example, sensitive and rapid determination of lead remains a substantial challenge for other techniques. X-ray fluorescence (XRF) has often been the method of choice because this technique requires no lengthy sample preparation. However, XRF analysis can take 1 to~ 10 min per sample in order to accumulate a detectable signal from low-parts-per-million concentrations of lead. And it can fail to detect even higher ...
