Abstract
In an automated analyzer that measures concentration of samples by comparing changes in a detector response caused by said samples to a calibration curve or factor based on one or more different calibration standards stored in the analyzer, a replacement calibration standard is validated automatically by processing a portion of said replacement calibration standard as a sample prior to accepting the new calibration standard as a valid standard.
