Tell me the correct usage method of the sampling bottle

2025-05-10

The correct use of sampling bottles Preparation before use Cleaning: New sampling bottles need to be thoroughly cleaned before use to remove any impurities and contaminants that may be present. Choose the appropriate cleaning method based on the material and purpose of the sampling bottle. For example, glass sampling bottles can usually be soaked in potassium dichromate solution, and then rinsed clean with tap water and distilled water in sequence; Plastic sampling bottles can be cleaned with mild detergent and then rinsed with pure water. For sampling bottles used for high-purity sample collection, special cleaning and passivation treatment may also be required. Drying: The cleaned sampling bottle should be dried to avoid moisture affecting the sample. The drying method can be selected according to the material and shape of the sampling bottle, such as drying, air drying, nitrogen blowing, etc. For some moisture sensitive samples, it is necessary to ensure that the inside of the sampling bottle is completely dry. Preprocessing (if necessary): Some special sample collection may require pre-processing of the sampling bottle. For example, when collecting volatile organic compound samples, in order to reduce the adsorption of the sample on the inner wall of the sampling bottle, a layer of an...
