II. Application Scenarios

1. Pharmaceutical industry: – In the process of drug production, strict cleaning of equipment is required between different batches of drug production to prevent cross-contamination. Cleaning verification swabs can be used to detect drug residues on the surface of production equipment such as reactors, filling machines, pipelines, etc. to ensure that the cleaned equipment meets the quality requirements of drug production. – For the production of highly active, highly toxic drugs, cleaning verification is particularly important, cleaning verification swabs can accurately detect very low levels of residues, to protect the safety of drugs.
2. Food industry: – In the cleaning validation of food processing equipment, cleaning validation swabs can detect food residues, cleaning agent residues and microbial contamination. For example, in the dairy processing equipment, beverage filling equipment and other cleaning verification, to ensure that the surface of the equipment no residual protein, sugar and other substances, to prevent cross contamination between different batches of food, to ensure the quality and safety of food.
3. Cosmetic industry: – Cosmetic production equipment also need to carry out strict cleaning verification, in order to prevent cross-contamination of ingredients between different products as well as microbial contamination. Cleaning verification swabs can be used to detect residues of active ingredients, fragrances, colors and other residues on the surface of cosmetic production equipment to ensure the quality and safety of cosmetics. **
   III. Testing and Analysis
4. Sample collection: – Use the cleaning verification swab to wipe the sample on the surface of the equipment, easy and convenient operation. A reasonable wiping program can be developed according to different equipment surfaces and cleaning requirements to ensure that representative samples are collected. – For some hard to reach parts, you can use a special shape of the cleaning verification swabs for sampling, to improve the comprehensiveness of the test.
5. Laboratory analysis: – Collected samples can be tested by various analytical methods, such as high performance liquid chromatography (HPLC), gas chromatography (GC), mass spectrometry (MS), etc., to determine the type and content of residues. – Microbiological testing, such as culture and rapid test methods, can also be performed to assess microbial contamination of equipment surfaces. In conclusion, cleaning verification swabs play a vital role in the cleaning verification process in various industries, which can provide companies with accurate and reliable cleaning inspection data to ensure the quality and safety of the production process.
