5.3 Standard solutions
5.3.1 Target compound stock solutions
Based on its tasks, a laboratory shall decide which compounds from Table 1 need to be determined. Based
on this decision, standard stock solutions for each compound (for example, c = 100 μg/ml for each
compound) shall be available either as commercially available certified mixes or individual components
in solution or as self-prepared individual or mixed standard stock solutions of each compound (Table 1)
in dichloromethane (5.1).
EXAMPLE For standard stock solutions with concentrations of 100 μg/ml, 25,0 mg of each compound
(Table 1) is weighed into a 250 ml volumetric flask, filled up to the mark with dichloromethane (5.1) and mixed
thoroughly to dissolve the compound completely.
5.3.2 Target compound working solution
Prepare a mixed working solution containing all required compounds in a suitable concentration for the
GC-MS system used (for example, c = 10 µg/ml).
5.3.3 Internal standard solution
Prepare an internal standard (IS) solution of a suitable concentration for the GC-MS system used (for
example, c = 1 µg/ml) by dissolving 2,4,5,6-tetrachloro-m-xylene (Table 1, Compound number 37) in
dichloromethane (5.1).
6 Apparatus
The usual laboratory apparatus and laboratory glassware, according to EN ISO 4787, shall be used, in
addition to the following:
6.1 Analytical balance, with a resolution of at least 0,1 mg.
6.2 Glass vials with tight closure, for example, 40 ml.
6.3 Ultrasonic bath.
6.4 Polytetrafluoroethylene (PTFE) filter, at maximum 0,45 μm pore size.
6.5 GC vial with cap, for example, 2 ml.
6.6 Gas chromatograph (GC), coupled with single-quadrupole mass spectrometer (MS) or triple-
quadrupole mass spectrometer (MS/MS).
7 Preparation of test specimens
The test specimen shall consist of a single material type (fibres, yarns, fabrics, coated fabrics or plastics).
Up to three test specimens (of equal mass) of the same material type can be tested together taking into
consideration the limits of quantification. Since different colours can contain different concentrations of
chlorobenzenes, chlorotoluenes, and α-chlorinated toluenes, each coloured material shall be considered
as one test specimen. Multicoloured material with small pattern shall only be tested as a single test
specimen.
Cut the test specimen into pieces of about 0,3 cm to 0,5 cm edge length and store them in a sealed glass
vial (6.2) until further processing.
8 Procedure
8.1 Extraction
Weigh (2,0 ± 0,1) g of the test specimen (7) in a glass vial (6.2), record the mass to the nearest 10 mg, add
20 ml IS solution (5.3.3) appropriate for the GC-MS system (6.6) used, and seal the vial. If less than 2 g of
test specimen is available, the test specimen mass shall be more than 0,5 g, and the volume of the
IS solution (5.3.3) shall be reduced proportionately. Extract the test specimen for (30 ± 1) min in an
ultrasonic bath (6.3) initially at laboratory ambient temperature.
After the extraction, let the solution cool down to nearly room temperature before opening the vial. Filter
the solution through a PTFE filter (6.4). Transfer an aliquot of the extract into a GC vial (6.5) and seal with
a cap.
8.2 Determination by GC-MS or GC-MS/MS
8.2.1 Preparation of calibration solutions
Prepare at least 5 calibration solutions of a mixture of the required compounds listed in Table 1, including
internal standard, from the working solutions (5.3.2), in dichloromethane (5.1), at suitable
concentrations for the analysis. Each solution shall contain the internal standard in a concentration that
matches the internal standard concentration in the extract (8.1).
8.2.2 Determination by GC-MS or GC-MS/MS
Determine the compounds listed in Table 1 extracted in 8.1 by GC-MS or GC-MS/MS (6.6) as required.
Examples of conditions for instrumental analyses by GC-MS and GC-MS/MS are given in Annex C.
It is known that particular compounds used for textile finishing may degrade at temperatures above
150 °C in a GC inlet and release α-chlorinated toluenes (see Annex A). Take quality measures to avoid
“false positive” results (Annex A). Examples of suitable instrumental parameters to avoid the for
