Determination of phthalate plasticizers in plastic blood bags Gas chromatography tandem mass spectrometry1 ScopeThis standard specifies the content of seven phthalate plasticizers in plastic blood bags (see Appendix A) for gas chromatography-mass spectrometry (GC/MS). Determination method and positive confirmation method. This standard applies to the determination and confirmation of various phthalate plasticizers in plastic blood bags.2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 The phthalate plasticizer is a carbon oxyhydroxide, and its chemical structure has the common characteristics. R-O-CO-C6H4-CO-O-R', ie There are two symmetric or asymmetric formic acid hydrocarbon esters ortho to the phenyl ring.3 Method summaryThe sample was ultrasonically extracted with chloroform. After the extract was fixed to volume, it was detected by gas chromatography-mass spectrometry and quantified by internal standard method.4 reagents and materialsUnless otherwise specified, the reagents used should be of analytical grade. 4.1 Trichloromethane. 4.2 phthalate plasticizer standard. purity ≥ 98%. 4.3 Standard stock solution. accurately weigh the appropriate amount of each phthalate plasticizer standard (see Appendix A), using chloroform Prepared as standard stock solutions at a concentration of 1000 mg/mL. 4.4 Mixed standard working solution. Dilute to a suitable concentration of mixed standard working solution with chloroform as needed. 4.5 Internal standard. Dipentyl phthalate. purity ≥ 98%. 4.6 Standard stock solution of internal standard. Accurately weigh the appropriate amount of diamyl phthalate standard, and prepare the concentration with chloroform Standard stock solution of 1000 mg/mL.5 Instruments and equipment5.1 Gas Chromatography-Mass Spectrometry (GC/MS). 5.2 Ultrasonic generator. power 500W. 5.3 Stainless steel mesh. The hole diameter is less than 0.5cm. 5.4 Erlenmeyer. Grinding plug, 100mL.6 Analysis steps6.1 Extraction Take 10 g of representative sample, cut it to 0.5 cm × 0.5 cm or less, and mix. Weigh the above 1.0g sample, accurate to 0.0001 g, placed in a 100 mL stoppered conical flask, added with 30 mL of chloroform, and extracted in an ultrasonic generator for 20 min. cool down ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 1779-2006_English be delivered?Answer: Upon your order, we will start to translate SN/T 1779-2006_English as soon as possible, and keep you informed of the progress.
