Analytical predictive capabilities of Laser Induced Breakdown Spectroscopy (LIBS) with Principal Component Analysis (PCA) for plastic classification

2013-01-01 K S Choudhari Suresh D Kulkarni Rajesh Nayak V B Kartha

2013, Royal Society of Chemistry. A Laser Induced Breakdown Spectroscopy (LIBS) technique has been applied for the identification of four widely used plastics, polyethylene terephthalate (PET), high-density polyethylene (PE), polypropylene (PP) and polystyrene (PS), whose recycling is required from commercial and biosafety points of view.

Analysis of Trace Elements in Complex Matrices (Soil) by Laser Induced Breakdown Spectroscopy (LIBS)

2013-01-01 Rajesh Nayak Kiran Aithal V B Kartha C Santhosh

2013, RSC Analytical Methods, Royal Society of Chemistry. Direct spectro-chemical analysis of trace elements in complex matrices like minerals and soil is usually difficult because of possible interference from the intense background spectrum of the major components generated in the plasma. Optimisation of the Laser Induced Breakdown Spectroscopy (LIBS) technique is essential for routine analysis of such samples. In the present work, we have shown that low detection limits can be achieved for trace elements like copper, zinc, and calcium in soil samples.
