Embodiment 1
[0016] a. Prepare a saturated aqueous solution of vitamin C in a brown bottle, weigh 200g of the solution in a beaker, slowly add 3g of starch-type sodium carboxymethylcellulose (CMC) to it under magnetic stirring, and stir to dissolve it completely. A solution with a viscosity of 1800 cp was obtained.
[0017] b. Coat the obtained solution on the inner wall of the fishtail hood for sidestream smoke measurement, rotate gently to make the coating even, and then hang the fishtail bottle in a light-proof and ventilated place to let it solidify naturally.
[0018] c. After the Cambridge filter used for suction is treated with 2ml of saturated aqueous solution of vitamin C, it shall be balanced according to the suction standard. Connect the prepared fish tail cover into the side stream catcher with the treated filter disc, connect it into the side stream pipeline to suck the mixed type reference cigarette, and extract the filter disc with dichloromethane after the suction is comple...
Embodiment 2
[0020] a. Prepare a 10% methanol solution of vitamin E in a brown bottle, weigh 100g of the solution in a beaker, slowly add 1g of sodium carboxymethyl cellulose to it under magnetic stirring, stir to make it fully dissolved, and obtain a viscosity of 1000cp solution.
[0021] b. Coat the obtained solution on the inner wall of the fishtail hood for sidestream smoke measurement, rotate gently to make the coating even, and then hang the fishtail hood in a light-proof and ventilated place to let it solidify naturally.
[0022] c. After the Cambridge filter used for suction is treated with 2ml of vitamin E in 10% methanol solution, it shall be balanced according to the suction standard. Connect the prepared fish tail cover into the side stream catcher with the treated filter disc, connect it into the side stream pipeline to suck flue-cured tobacco type reference cigarettes, and extract the filter disc with dichloromethane after the suction is completed. Concentrate, purify by bas...
Embodiment 3
[0024] a. Prepare a 5% ethanol solution of carotene in a brown bottle, weigh 200g of the solution in a beaker, slowly add 2g of starch-type carboxymethylcellulose (CMS) to it under magnetic stirring, and stir to dissolve it completely. A solution with a viscosity of 1500 cp was obtained.
[0025] b. Coat the obtained solution on the inner wall of the fishtail hood for sidestream smoke measurement, rotate gently to make the coating even, and then hang the fishtail bottle in a light-proof and ventilated place to let it solidify naturally.
[0026] c. After the Cambridge filter used for suction is treated with 2ml of carotene in 5% ethanol solution, it shall be balanced according to the suction standard. Connect the prepared fish tail cover into the side stream catcher with the treated filter disc, connect it into the side stream pipeline to suck the mixed type reference cigarette, and extract the filter disc with dichloromethane after the suction is completed, Concentrate, puri...
