The method includes taking a first reading of particles count of a sample placed into a chamber. The method further includes directing a stream of air over the sample, and taking a second reading of particles count of the sample. The method further includes calculating a difference between the first reading and the second reading, and determining a cleanliness of the sample based upon the difference. The method further includes option of taking an additional reading while a stream of ionized air is directed towards the sample. The method further includes trapping the impurities particles released from the sample by applying a vacuum through the filter, and analyzing the trapped particles to determine nature and chemical composition of the impurities particles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for determining cleanliness of a sample","description":"A method and apparatus for determining cleanliness of a sample is provided.
