Interferences in the quartz tube atomizer during arsenic and antimony determination by hydride generation atomic absorption spectrometry

Separation of trace antimony and arsenic prior to hydride generation atomic absorption spectrometric determination

“…The effect of KI on the interferences by Bi, Se and Te on Sb signal and the interferences of Sb, As, Bi, Te, and Sn on the Se signal using oxygen and a mixture of ozone were examined by Barth et al [11]. In a study by Ay and Henden [12], a separation procedure using a GC column was applied to eliminate the inter-element interference of arsenic and antimony. In the GC column, arsine is eluted first and separated from stibine.…”

Design and evaluation of a continuous flow, integrated nebulizer-hydride generator for flame atomic absorption spectrometry

“…Nevertheless, frequent use may irrecoverably modify the surface with the consequence of a reduction in sensitivity. It has also been reported 16,17,19,20 that the original performance is not obtained by cleaning the tube. These interferences are reduced by 2 to 3 orders of magnitude by using either a hydrogen flame in QTA, 6 a miniature argon hydrogen flame, 2,21 a flame-in-gas-shield atomizer, 21 a multiple microflame QTA 22 or a long-path slot burner.…”

Evaluation of Arsenic Concentration in Poultry and Calf Meat Samples by Hydride Generation Atomic Fluorescence Spectrometry

“…ROX is a compound that has low toxicity; however, the studies showed that its continuous usage could lead toxicity since it is transformed into i-As in chicken tissues [7,8]. The atomic techniques such as inductively coupled plasma mass spectrometry (ICP-MS) [9][10][11][12][13][14][15], hydride generation atomic absorption spectrometry (HG-AAS) [16][17][18][19][20][21] and hydride generation atomic fluorescence spectrometry (HG-AFS) [22][23][24][25] are widely used to determine arsenic in various samples. It is well known that the use of HG can improve the sensitivity and the selectivity in arsenic determination.…”
