Why do food/drink industries and pharmaceutical companies use qualitative analysis?
I am sure that we want our food and drug industries to be supplying pure food and medicines. China has shown recently how things can go wrong when what goes into foods or drugs can go far astray.
I worked quality control for a large food supply company in CA, where we checked daily on all the foods we were sending out. My son-in-law does qualitative analysis for a drug company making sure all runs of a drug are correct.
