Interlaboratory Evaluation of SW-846 Methods 7470 and 7471 for the Determination of Mercury in Environmental Samples

摘要

The EPA protocols for SW-846 Methods 7470 and 7471 are cold-vapor atomic absorption spectrometric (CV-AAS) methods for the determination of mercury in aqueous and solid environmental samples. In continuation of a previous single-laboratory study in which a revised more sensitive mercury CV-AAS method for environmental analyses was evaluated, the revised CV-AAS method has been subjected to an interlaboratory study.
