HPLC and GC-MS detection of compounds released to mineral waters stored in plastic bottles of PET and PVC

The migration of certain compds. from PET [poly(ethylene terephthalate)] and poly(vinyl chloride) bottles to waters was studied by HPLC with UV detection after extn. with di-Et ether. Compds. in mineral waters were identified by gas chromatog.-mass spectrometry (GC-MS). Erucamide, from PET bottles, was quant. detd. in some mineral waters. Two other compds., also detected in mineral waters stored in PET, were identified as low-mol.-wt. cyclic oligomers produced during the PET polymn. process
