Simple Definition of Standard and Control in Laboratory

In a laboratory, a standard is a known quantity of a substance that is used as a reference point for comparison with other samples or measurements. Standards are typically well-characterized and have a known composition, concentration, or purity.

On the other hand, a control is a sample or measurement that is used to ensure that a laboratory procedure is working properly and that the results are reliable. It is usually prepared in the same way as the samples being tested but are known to have a specific value or concentration that is used to verify the accuracy and precision of the laboratory procedure. It also used to monitor for contamination or to evaluate the performance of laboratory equipment.
