| dc.description | A continuous-fl ow hydride generation system was developed and used with inductively coupled plasma optical emission spectrometry (ICP OES) for simultaneous determination of As, Sb and Se in agronomic samples. A factorial design was applied in order to establish the best chemical and instrumental conditions. The factors chosen for evaluation were: reagent concentration, plasma power, carrier gas fl ow rate, and the viewing height of the plasma. The LODs of the method were 0.124, 0.168, and 0.141 ?g L-1 for As, Sb, and Se, respectively. The RSD (relative standard derivation) was lower than 1.8%, and the sampling throughput was 40 samples h-1 . To check the method accuracy, eight different kinds of agronomic samples - for- age, corn silage, mineral salt, and bovine-derived samples (blood, viscera, carcass, meat, and semen) - were spiked with different analyte concentrations (at the ?g L-1 level). Recoveries ranged from 90 to 102%. | |
