A method batch, as defined by the United States Environmental Protection Agency via its SEDD Specification Version 5.2, is "a laboratory-defined identifier that is used to link multiple samples analyzed by one method and treated as a group for quality control (QC) purposes. A method batch should group samples with similar matrices and potential interferences." The EPA adds the following[1]:
This is a broader grouping than a preparation batch. In particular, a reanalysis of a sample stays in the same method batch, while it is likely to be in a different preparation batch. Operationally, this batch associates sample dependent QC such as duplicates and matrix spikes with a group of samples that may or may not be prepared at the same time.
