Adipate such as DEHA in P犞C food wrap film Determination of plasticizers - gas chromatography tandem mass spectrometry

1 Scope

This standard specifies the method for determining the content of DEHA and other adipate plasticizers in PVC food wrap film by gas chromatography-mass spectrometry. Positive confirmation method. This standard applies to the determination and confirmation of the content of DEHA and other adipate plasticizers in PVC food wrap.

2 Terms and definitions

The following terms and definitions apply to this standard. 2.1 The molecular structure of the adipate plasticizer such as DEHA is. R1-CO-C4H8-CO-R2. This type of substance mainly contains diethyl adipate Diethyl adipide (DEA), diisobutyladipate (DIBA), dibutyl adipate (dibu-) Tyladipate (DBA), bis(2-butoxyethyl)adipate, BBOEA and hexane Di(2-ethylhexyl)adipate (DEHA). 2.2 Internal standard. bis(1-butylpentyl)adipate (BBPA).

3 Method summary

The sample was ultrasonically extracted with isopropyl alcohol, and the extract was fixed to volume and then detected by gas chromatography-mass spectrometry and quantified by internal standard method.

4 reagents and materials

Unless otherwise specified, the reagents used should be of analytical grade. 4.1 Isopropanol. 4.2 DEHA and other adipate plasticizer standards. purity ≥ 98%. 4.3 DEHA and other adipate plasticizer standard stock solution. accurately weigh the appropriate amount of DEHA and other adipate plasticizer The standard product was prepared into a standard stock solution with a concentration of 10 mg/mL using isopropyl alcohol. 4.4 Internal standard. di(1-butylpentyl) adipate. purity ≥98%. 4.5 Internal Standard Standard Stock Solution. Accurately weigh the appropriate amount of di(1-butylpentyl) adipate standard and prepare the concentration with isopropanol. Standard stock solution of 10 mg/mL. 4.6 Mixed standard working solution. Take appropriate amount of internal standard standard stock solution and standard stock solution of adipate plasticizer such as DEHA, root Dilute to a suitable concentration of the standard working solution with isopropanol as needed.
