Although attention was paid to avoid potential contamination: 1) use of plasticizer-free material, 2) use of new bottle of high purity solvent (of LC–MS grade), 3) bi-distilled
As plasticizers are not chemically bound to PVC, they can be released from the medical device during contact with blood, enteral or total parenteral nutrition admixtures, or

However, a noticeable difference between PVC and liquefied DME extracted residues is observed, where a peak around 1041 cm −1 is identified as planar ring vibrations

This occurs because plasticizers are bulky, polar, organic molecules that decrease the intermolecular interactions between the chains of a crystalline polymer, making it more flexible
- Can NMR detect traces of DEHP in PVC medical devices?
- Genay et al. used NMR to identify traces of DEHP in PVC medical devices presented as DEHP-free, i.e., with an amount lower than 0.1% . However, Lutyten et al. identified several drawbacks, including low sensitivity, while working on the quantification of different plasticizers present in PVC tubes.
- Can plasticizers replace DEHP in blood bags?
- Several plasticizers have been suggested as substitutes to DEHP in blood bags. Di(2-ethylhexyl) terephthalate (DEHT) and di-isononyl cyclohexane-1,2-dicarboxylic acid (DINCH) have shown the greatest potential so far, despite providing inferior RBC quality in previous studies [9 13].
- How to avoid DEHP contamination from the LC system?
- The establishment of a trap column, as described above, is a successful set-up avoiding DEHP contamination came from the LC system. However, first experiments relative to the development of LLE method revealed other sources of DEHP contamination those concentration determined by LC–MS/MS analysis saturated the MS detector.
- Is DEHP contamination from LC system favored by a mobile phase?
- After deep investigation, we concluded that DEHP contamination came from the LC system and was favored by using a mobile phase with a high content of ACN. In order to discriminate DEHP contamination and DEHP present in the sample, a trap column was implemented on the system ( Fig. 3) as proposed by Vavrous et al. [ 25 ].
- Is DEHP leachable from PVC-blood bags?
- The optimized method was applied to evaluate the leachability of DEHP or DINCH from PVC-blood bags and to determine the concentration of their corresponding metabolite MEHP and MINCH in the four LBP. Blank sample was performed every five analyses in order to verify that no carryover occurred.
- Is DEHP a toxicity hazard?
- The European Directive 2007/47/CE, classified DEHP as a product with a toxicity risk and restricted its use in MDs. MD manufacturers were therefore forced to quickly find alternatives to DEHP to maintain the elasticity of PVC nutrition tubings, infusion sets and hemodialysis lines.
