Atomic Absorption Control of Ultimate Allowable Concentration of Elements in Meat Products without Sample Dissolution

Abstract

Abstract: In order to control the maximum levels of As, Cr, Pb, Cd, and Sn in meat products, it is proposed to transfer them to a suspension of 140 mg/mL and use an atomic absorption spectrometer with a graphite furnace, equipped with a probe attachment for a two-stage atomization of the suspension. The working linear range covers 0.2–9 ultimate allowable concentrations. The error is smaller by factors of 2 to 3 than that of the methods with sample dissolution, and it saves at least 12 h in time.
