Quality control refers to the sum of all procedures undertaken to ensure the identity and purity of a particular pharmaceutical product. Such procedures may range from the performance of simple chemical experiments which determine the identity and screening for the presence of particular pharmaceutical substance to more complicated requirements of pharmacopoeial monographs.
The quality of a product may deviate from the standard required so carrying out analysis is important in order to determine the quality. Testing a pharmaceutical product involves chemical, physical, and some time microbiological evaluation or test.
Quality control (QC) is a process through which a business seeks to ensure that product quality is maintained or improved. Quality control requires the business to create an environment in which both management and employees strive for perfection.
Quality control involves testing of units and determining if they are within the specifications for the final product.
The quality control used in a business is highly dependent on the product or industry, and several techniques exist for measuring quality.
