Extraction, identification and determination of di-(2
Abstract The di- (2-ethylhexyl) phthalate (DEHP) was extracted using different solvents from plastic blood bag. The purified product was identified using FT-IR, NMR (1H and 13C), DEPT, COSY,...
Identification of plasticizers in medical products by a
Extraction of the common plasticizer di (2-ethylhexyl) phthalate (DEHP) into blood will occur, and harmful effects of DEHP in the human body have been suggested. We therefore analyzed 21 different plastic devices which are used for various invasive techniques in medicine by direct thermodesorption GC-MS.
- How are plasticizers extracted?
- In their study, plasticizers were extracted by dissolving PVC samples in THF and precipitating with ethanol . The extraction yields of plasticizers (from 91 to 120%) were similar to results presented in our paper (from 91 to 104%), but with greater variability.
- Which plasticizers were separated by Gradient elution?
- Five plasticizers, acetyl tributyl citrate, di- (2-ethylhexyl)-phthalate, di- (ethylhexyl)-terephthalate, di-isononyl-1,2-cyclohexane-dicarboxylate, and trioctyl trimellitate, were separated on a C8 stationary phase (2.6 μm, 100 mm × 4.6 mm) under gradient elution in 13 min.
- How are plasticizers extracted from PVC-tubing?
- Plasticizers were extracted from PVC-tubing by dissolving PVC in THF then precipitating it in methanol with a yield of over 90% for each plasticizer. This assay could feasibly be used to quantify plasticizers in PVC medical devices. 1. Introduction
- Can plasticizers be extracted from PVC tubing?
- Hence, the extraction yields (% w/w of PVC sample) from PVC tubing were 96.9 ± 2.5%, 103.7 ± 0.5%, 94.0 ± 1.6%, 90.6 ± 1.8% and 99.7 ± 0.5% for ATBC, DEHP, DEHT, DINCH and TOTM, respectively ( Table 5 ). Based on these results, this extraction technique seems to be adapted to the extraction of these plasticizers from PVC tubing. Table 5.
- Can plasticizers be quantified by GC–MS?
- Gimeno et al. recently published a new GC–MS technique to quantify 19 plasticizers in a single run. Among their tested compounds ATBC, DEHT, DINCH and TOTM were also analyzed. In their study, plasticizers were extracted by dissolving PVC samples in THF and precipitating with ethanol .
- What are the limits of quantification of PVC plasticizers?
- The reported limits of quantification were 5 μg/mL and 25 ng/mL, respectively. After extraction from PVC tubes by diluting with THF and precipitating PVC with ethanol, the plasticizers were quantified by GC–MS with high sensitivity (LOD between 0.06 and 0.25 μg/mL and LOQ between 0.01 and 2.0 μg/mL, depending on the plasticizer).
