  • Which method is used to identify plasticizers?
  • Gas chromatography (GC) and liquid chromatography (LC) are the preferred indirect methods for the identification of plasticizers.
  • Why is mass spectroscopy a good method for detecting plasticizers?
  • Mass spectroscopy is the most suitable method for the simultaneous detection and quantification of mixtures of low concentrations (or traces) of plasticizers because it provides selectivity and sensitivity in the analysis of complex samples. Wang et al. found DEHA in two out of three tubes using GC/MS analysis .
  • Can GC-MS detection of plasticizers be easier?
  • The authors demonstrated that using this extraction technique made the GC–MS detection of the plasticizers easier, allowing a detection limit below 0.1 mg/kg for plasticizers forming single peaks and 1 mg/kg for mixtures of isomers, like DINP. Also, the analysis presupposes a higher injector temperature than usual.
  • How LC method is used to analyze metabolites of alternative plasticizers?
  • LC methods for determination of trace levels of metabolites of alternative plasticizers from urine samples. LC is the preferred method to analyze metabolites of alternative plasticizers, mainly due to the high separation capability and because it is a conventional technique in most laboratories conducting trace analysis.
  • Can a rapid screening test for plasticizers be developed using DART-MS?
  • It was also successfully used by Rothenbacher et al. to determine if a rapid screening test for plasticizers (like DEHP, DINP, or DINCH) in PVC materials can be developed using direct analysis in real time mass spectrometry (DART-MS). An open interface would allow the direct insertion of solid specimens, such as samples of medical devices.
  • How is NMR used to study polymer-plasticizer interactions in plasticized systems?
  • NMR is used to study microstructures and polymer-plasticizer interactions in plasticized systems. For example, a combination of a 13C solution and solid state NMR was used to reveal the crystallinity of PVC-DEHP samples that contained PVC of different tacticities .
