An aliquot is the fraction or measured part of a sample or specimen that is removed and placed in a different container for testing.[1][2] For purposes of reporting, the amount of aliquot used in a given test is "the amount (weight or volume) of sample subjected to an analysis," or, "if the analytical method requires the prior use of an independent preparative method, [it] is the amount of sample subjected to the preparative method prior to actual analysis of the sample."[3]
