On the use of noble metals modifiers for simultaneous determination of As, Sb and Se by electrothermal atomic absorption spectrometry

Surface studies on graphite furnace platforms covered with Pd, Rh and Ir as modifiers in graphite furnace atomic absorption spectrometry of tellurium

“…In fact the permanent modification needs both: the choice of the chemical compound and a method for coating that is able to control the size and distribution of the particles of the modifier onto the graphite platform. On the knowledge that the characteristics of the coating are related to the mechanisms of action of the modifiers [4,15,20,28,29], Spectrochimica Acta Part B 107 (2015) 152-158 ⁎ Corresponding author.…”

Investigation of aging processes of graphite tubes modified with iridium and rhodium used for atomic spectrometry

“…When electrothermal atomization is applied, special attention is always placed on the use of modifiers, especially noble metals that, since their introduction, are undoubtedly the most often employed [6]. In fact, much work has been done towards the application of noble metals modifiers for various analytes and matrices [7,8], and towards understanding the mechanisms of the analyte-modifier and substrate-analyte-modifier interactions [9][10][11][12]. An expected advantage of the modifier is improved long-term performance, and it was justified that noble metals modifiers could be used for this purpose [13][14][15].…”
