Analysis of PVC plasticizers in medical devices and infused solutions by GC¨CMS - ScienceDirect

Introduction In 2008, di- (2-ethylhexyl) phthalate (DEHP), widely used as a plasticizer in flexible polyvinyl chloride medical devices (PVC MDs), was categorized as CMR 1B (carcinogenic, mutagenic or toxic to reproduction) under the CLP regulations [1].

Identification and quantification by 1 H nuclear magnetic resonance spectroscopy of seven plasticizers in PVC medical devices - Springer

The main objective of this study was to propose a new method using 1 H NMR spectroscopy to determine and quantify these seven plasticizers in PVC sheets, standard infusion tubings, and commercially available medical devices. Two techniques were compared: dissolution in deuterated tetrahydrofuran and extraction by deuterated chloroform.

Abstract. A GC/MS method was developed for the identification and quantification of 14 phthalates: 8 phthalates classified H360 (DBP, DEHP, BBP, DMEP, DnPP, DiPP, DPP and DiBP), 3 phthalates proposed to be forbidden in medical devices (DnOP, DiNP and DiDP) and 3 other phthalates none regulated (DMP, DCHP and DEP) which may interfere with
