There are two general reasons for performing separations on mixtures. First, the mixture may contain some substance that should be isolated from the rest of the mixture : this process of isolating and thus removing substances considered to be contaminants is called purification.... The second reason for performing separations is to alter the composition of a sample so that one or more of the components can be analyzed.... several impurities in a sample may interfere with the analysis of the substance of primary interest.  5, record 1, English, - purification

It is particularly relevant to fermentation processes, which produce a large amount of a dilute mixture of substrates, products, and microorganisms. These must be separated, the product concentrated and purified, and converted into a product which is useful. There are three general steps to downstream processing : separation, concentration and purification.  3, record 2, English, - downstream%20processing
