Abbreviations: GM, grand mean; SD, standard deviation; DEV, percent deviation from nominal value; BRP, between run precision; WRP, within run precision; n, total number of replicate observations within the validation runs.

Four or five samples at each concentration were analyzed on four different occasions.
