Classification of polymers by determining of C1:C2:CN:H:N:O ratios by laser-induced plasma spectroscopy (LIPS)

TL;DR: In this paper, a new approach for the determination of major elemental ratios in organic compounds such as polymers by using laser-induced plasma spectroscopy (LIPS) was investigated.
Journal ArticleDOI

Rapid characterization of plastics using laser-induced plasma spectroscopy (LIPS)

TL;DR: In this article, a laser-induced plasma spectrometry (LIPS) was used to identify post-consumer plastics by comparing the LIP spectra from polyethylene terephthalate (PET) and polypropylene (PP) with reference spectral libraries stored in a computer.
Journal ArticleDOI

Identification of polymers by libs using methods of correlation and normalized coordinates

TL;DR: In this article, a new statistical method, linear and rank correlation have been applied to identify polymers with a very similar chemical composition by laser-induced breakdown spectroscopy (LIBS), which provided effective identification and discrimination at a 95% confidence level.
Journal ArticleDOI

Discrimination of organic solid materials by LIBS using methods of correlation and normalized coordinates

TL;DR: Methods of correlation provide better identification and discrimination than normalized coordinates at a 95% confidence level and can be estimated by means of the described methods in this paper.
Journal ArticleDOI

Quantitative analysis of oxide materials by laser-induced breakdown spectroscopy with argon as an internal standard

TL;DR: In this paper, the contents of several oxides, such as Fe2O3, CaO and MgO, in geological samples from the Tierga Mine (Zaragoza, Spain) were analyzed by LIBS.
