Avaliação de tratamentos da amostra em microescala para a determinação de K, Mg, Na e Zn em carnes por técnicas de espectrometria atômica

Abstract: Recebido em 28/9/12; aceito em 19/2/13; publicado na web em 15/4/13 EVALUATION OF SAMPLE TREATMENT IN MICRO-SCALE FOR THE DETERMINATION OF K, Mg, Na AND Zn IN MEAT BY ATOMIC SPECTROMETRY TECHNIQUES. This paper describes the development of methods in micro-scale for the determination of K, Mg, Na and Zn in meat by atomic spectrometry techniques. The limits of detection (LOD) for K and Na by microdigestion were 0.18 and 0.20 mg g -1 , respectively whereas LOD for Mg and Zn by microsolubilization with TMAH were 2… Show more

“…passing the main problem of conventional decomposition methods, which use substantial amounts of both sample and reagents, interfering directly with the cost of analysis and waste generation. [14][15][16][17][18] A great number of these studies was performed in centrifugation micro tubes made of polypropylene, which limits time and temperature decomposition. Consequently, a micro tube deformation and rupture occurs, affecting the efficiency and repeatability of the procedure.…”
