1 Scope

This standard specifies the method for the determination of 4-methylbenzophenone and benzophenone in inks for food contact materials by gas chromatography-mass spectrometry. This standard applies to the determination of 4-methylbenzophenone and benzophenone in inks for food contact materials.

2 Method summary

The ink sample was ultrasonically extracted by n-hexane, fixed to volume, filtered by 0.45 μm filter, directly analyzed by gas chromatography and mass spectrometry, and selected for ion detection. Measurement, external standard method quantitative.

3 reagents and materials

The reagents used were of analytical grade unless otherwise stated. 3.1 Benzophenone (C13H10O, CAS No.. 119-61-9). Purity greater than 99.0% (mass fraction). 3.2 4-methylbenzophenone (C14H12O, CAS No.. 150-76-5). purity greater than 99.0% (mass fraction). 3.3 n-hexane. 3.4 Standard stock solution of benzophenone and 4-methylbenzophenone (1.0mg/mL). accurately weigh benzophenone (3.1) and 4-methylbenzophenone Ketone standard (3.2) 0.1g each in a 100mL volumetric flask, accurate to 0.0001g, dissolved in n-hexane (3.3) and dilute to the mark, 0 ° C ~ 4 ° C sealed and protected from light. 3.5 filter, 0.45μm, nylon material.

4 Instruments and equipment

4.1 Gas Chromatography Mass Spectrometer. with EI ion source. 4.2 Ultrasonic generator. no less than 180W. 4.3 Analytical balance. Sensitivity 0.1mg.

5 Analysis steps

5.1 Preparation of sample test solution Accurately weigh 0.1 g of the ink sample (accurate to 0.0001 g) in a 100 mL stoppered conical flask. Add 20mL positive to the conical flask Hexane (3.3) was ultrasonically extracted for 30 min and allowed to stand. The extract was filtered and made up to 25 mL with n-hexane (3.3) through a 0.45 μm microporous membrane. (3.5) After filtration, it was analyzed by gas chromatography mass spectrometry. Note. For viscous samples, stir the sample well before weighing.
