Portable Raman Spectroscopy for Screening of Phthalate Plasticizers in Food Contact Production Line Tubing and Bottle Cap Gaskets.

ABSTRACT: In this work, we evaluate two commercially available portable Raman spectrometers for their ability to accurately determine the presence of ortho-phthalate ester plasticizers, hereafter referred to as phthalates, in poly(vinyl chloride) (PVC) food contact production line tubing. Further, we aim to identify individual plasticizer compounds in the PVC tubing from a panel of multiple components with portable Raman spectroscopy. This is accomplished through library spectral matching of unknown tubing samples with on-instrument library Raman spectra. This library matching methodology functions via the comparison of Raman spectra between unknown food contact tubing samples and a panel of previously scanned, known tubing samples. In both known and unknown tubing, the samples are also analyzed via
