Quality control laboratory. View of a chemistry laboratory used to perform quality control tests. Samples are taken from production batches at random and subjected to a standard series of tests. If any test is failed, the whole production batch is rejected. The results of a test may also help identify any problem in production. This method is used in a wide variety of industries as diverse as drug manufacture and industrial dyes.
