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

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.
