Atomic absorption spectrometry - a valuable tool for trace and ultratrace determinations of metals and metalloids in biological materials

摘要: Abstract This paper commences with a review of important improvements in Atomic Absorption instrumentation particularly benefit for the performance analyses biological materials. is followed by examples optimization initial steps analytical procedures and new instrumental concept ultratrace analysis mercury cold-vapour technique. Further proven still useful as well methodological approaches determination mercury, arsenic, cadmium, lead nickel, mainly body fluids, at normal elevated levels are summarized from experience author, which not only demonstrates present future potential but also some obviously existing limitations.
