Component used for reference present in or added to a sample to perform calibration, to assist in the identification of a chemical species, or as part of procedure validation.

Note 1: An internal standard provides an indication that varies in the same way as that of the analyte during chemical analysis. The ratio of the indications for analyte and internal standard provides a quantity value that can be used in calibration.

Note 2: In multicomponent mixtures, a component that is known to be in con- stant concentration or content across samples can be used as an internal standard.
