It is applicable to the determination of the pH value of 10% aqueous extract in Tobacco and Tobacco products. The determination method is determined by citing documents such as GB/T 5606.1, GB/T 9724 and GB/T 19616. The principle is that after the ground sample is extracted with water, its pH value is determined with an acidity meter. The required equipment includes a pulverizer, sieve, acidity meter, Balance, conicalflask and automatic Shaker. The reagents include standard buffer solution, electrode storage solution and swallow distillation water. The sampling method is carried out in accordance with relevant standards to ensure the representativeness of the sample.
