3 Method summary

The residual 2,4,6-trichloroanisole in the sample is adsorbed by the high-purity helium gas in the trap tube, and the trap tube is heated to a high purity helium gas. After backflushing, the target components thermally desorbed were separated by gas chromatography and detected with a mass spectrometer and quantified by an internal standard method.

4 Reagent materials

Unless otherwise stated, the reagents used were of analytical grade and water was a grade of water specified in GB/T 6682. 4.1 Methanol. Chromatographically pure. 4.2 Sodium chloride. 4.3 Standard crystal. 2,4,6-Trichloroanisole, CAS No. 87-40-1, purity >99%. 4.4 2,4,6-trichloroanisole standard stock solution (1000μg/mL). Accurately weigh 0.1g (accurate to 0.1mg) of the trichloroanisole standard product. Dissolve the methanol and bring it to 100 mL. Mix well and store for 3 months. 4.5 2,4,6-trichloroanisole standard intermediate solution (1μg/mL). Accurately remove 0.1mL of trichloroanisole stock solution in 100mL capacity In the bottle, dilute to the mark with methanol, mix, and use now. 4.6 2,4,6-trichloroanisole standard working solution (10μg/mL). Accurately remove 0.1mL of trichloroanisole intermediate solution in 10mL capacity In the bottle, dilute to the mark with methanol, mix, and use now. 4.7 Isotope internal standard. 2,4,6-Trichloroanisole-D5 internal standard (2,4,6-trichloroanisole-D5), purity >95%. 4.8 2,4,6-trichloroanisole internal standard stock solution (1000μg/mL).
