It is prepared and analyzed in the identical manner as the representative sample. The results from replicate analyses are used to evaluate analytical precision.
Laboratory replicate sample means a duplicate sample of the primary sample used for quality control purposes to demonstrate reproducibility. It is prepared in the identical manner as the primary sample and analyzed separately from the primary sample.
