This standard is equivalent to Japanese Industrial Standard J13K41C21995 formulated by the United States: The aerosol Xeno method is used to determine the content of o-dioxygen and the total amount of organic impurities; The Carlsbad method is used to determine the moisture content! The difference between this standard and Japanese industrial standard JTSK4102-1S95 is as follows: the fixed liquid used in this standard is 7.20MPFG-2CM); the carrier is 271 red carrier of 149-177um, while the fixed liquid used in Japanese industrial standard 1S4132-19V5 is 1HERM0R1000 and the carrier is ChuawurbHP1-.
一H This industrial standard J:SK102一1SS5 is set\not selected\item and index: because this index has little effect on the quality of dichlorodichloroethane, and the\non-volatile matter" item is kept for a month to support the production process, so it is not listed in this standard. The original Ministry of Chemical Industry of the People's Republic of China has made a special decision on the technical supervision of this standard. The original standard is proposed by the National Standardization Technical Committee of the People's Republic of China. The starting units are: Shenyang Huagong Research Institute, Luoyang Donghua Industrial Corporation, Shanle Province Pesticide 1 Industry Co., Ltd.

Weigh 0.1g potassium carbonate + 100m In the above method, add 20g of carrier body and stir until the chemical is completely dissolved, then pour 30g of carrier body into the beaker, and make it completely moist (about 30min). Place the beaker in a ventilated room, under a red light, let the solvent evaporate slowly to the bottom, then move to an oven for drying for about 10min, take 3.0g of the solution 7.20mL of dry 10ml. Add 20mL of hydrogen methane into the beaker to make it completely dissolved, and then add the carrier that has been burned to make it completely moist (about 30min). Place the beaker in a ventilated room, under an infrared light, slowly control the solvent level to 10 (tap the beaker frequently, remove oil quickly). Then adjust the temperature to 90- -100℃ oven for about 33min, then set aside. 5.3.3.3 Filling of stationary phase.
