激光诱导击穿光谱已被应用到聚合物样品，以研究使用这种方法用于识别不同材料的可能性。本文研究了高密度聚乙烯（HDPE）、低密度聚乙烯（LDPE）、聚氯乙烯（PVC）、聚对苯二甲酸乙二醇酯（PET）和聚丙烯（PP）的等离子体发射光谱。光谱特征已被测量，例如，725.7 nm的氯线，486.13 mm的H-β线，和247.86 nm的碳线，其评估与神经网络允许识别精度在90%和100%之间，这取决于聚合物类型。
Laser-induced breakdown spectroscopy has been applied to polymer samples in order to investigate the possibility of using this method for the identification of different materials. The plasma emission spectra of high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC), polyethylene terephthalate (PET), and polypropylene (PP) have been studied. Spectral features have been measured-for example, the 725.7 nm chlorine line, the 486.13 mm H-beta line, and the 247.86 nm carbon line-whose evaluation with neural networks permits identification accuracies between 90 and 100%, depending on polymer type.
