RAPID SURVEY ANALYSIS OF POLYMERIC MATERIALS BY LASER-INDUCED PLASMA EMISSION-SPECTROMETRY

Laser-induced plasma emission spectrometry has been applied to the ana lysis of poly(vinyl chloride) materials. Methodologies used to optimiz e the monitoring of the time-dependent emission from the laser-induced plasma are discussed, and the effects of key parameters, such as lase r energy, sample position and repetitive firing at given sites, were e xamined. Basic performance data are reported for Ca [limit of detectio n 0.016% m/m and 4.8% relative standard deviation (RSD)] and Sb (limit of detection 0.04% m/m and 4.8% RSD) and the potential use for rapid survey analysis is demonstrated.
