28、tely qualified and experienced people.1 ScopeThis part of ISO 17881 specifies a test method for determining some brominated flame retardants in textiles by gas chromatography mass spectrometry (GC-MS).The method is applicable to all kinds of textile products.2 PrincipleThe flame retardants are extra

29、cted from textile specimen by ultrasonic generator with toluene. The flame retardants in the specimen are identified by GC-MS and quantified by using internal standard method.3 ReagentsUnless otherwise specified, use only reagents of recognized analytical grade.3.1 Monobromobiphenyl (MonoBB), CAS no

37、tion (5.1.2) and dilute it to a series of suitable concentrations depending on test needs. Select at least five dilutions of the calibration sets to create calibration curve and perform GC-MS analysis.5.2 Preparation of test specimenPrepare a representative test specimen of the sample. Cut it into s

38、mall pieces and weigh (1,00 0,01) g of the pieces with a balance (4.7).5.3 Ultrasonic wave extractionPut the pieces in a vial with tight closure (4.4) and add 20 ml of toluene. Place the vial in an ultrasonic generator (4.2) and extract the pieces for 30 min at room temperature. Filter and transfer

39、the extract into 100 ml flask (4.5). Add 10 ml of toluene to the residue in the vial and place the vial in the ultrasonic generator to extract the residue for 15 min at room temperature. Filter and merge the extract into the flask (4.5).Evaporate the extract to near dryness by evaporator device (4.3

40、). Add 2 ml of internal standard solution (5.1.2) to dissolve the residue and then filter by filtration membrane (4.6). The filtrate is ready for determination of flame retardants.5.4 Flame retardants determinationDetermine the flame retardants in the solution (5.3) by GC-MS (4.1). The test paramete

41、rs by GC-MS are given in Annex A as an example. Run a blank to control contamination.When the flame retardants level is very low, it is necessary to increase the mass of the pieces in order to reach at least three times the detection limit.When the flame retardant level is beyond the linear detector

42、 response range of the equipment, it is necessary to dilute the specimen liquid properly.6 CalculationQuantify the concentration of each flame retardant by using the calibration curve. The content of each flame retardant is expressed by the mass ratio of flame retardant to test specimen, in g/g. Cal
