Investigation of problems associated with the determination of iodine in glacial acetic acid samples using flow injection analysis-inductively coupled plasma-mass spectrometry†

Dilute-and-shoot procedure for the determination of mineral constituents in vinegar samples by axially viewed inductively coupled plasma optical emission spectrometry (ICP OES)

“…The introduction of acid solutions with physical properties different from water in the plasma may modify the characteristics of the aspirated solution and, consequently, the aerosol formation and transport processes. This latter effect is especially critical when organic acids are employed (Roncevic and Siroki 1994;Korn and de Oliveira 1998;Rizzon and Miele 1998;Dubuisson et al 1998a;Ackley et al 1999;Todoli and Mermet 1999;Silva et al 2003).…”

“…Some studies concerning organic acid effects on ICP OES have been presented (Roncevic and Siroki 1994;Korn and de Oliveira 1998;Dubuisson et al 1998a;Ackley et al 1999). Roncevic and Siroki (1994) studied the effects of acetic acid on Mn II, Li I, Cu I, Cd I, and Cd II analytical emission lines using a radial viewed ICP OES.…”

“…According to Maestre et al (1999) and Todoli and Mermet (2000), the choice of the sample introduction system has an important effect on both matrix effect and nebulization efficiency. Ackley et al (1999) determined iodine in glacial acetic acid using flow injection analysis coupled to ICP-MS and ammonium hydroxide solution (3.7-7.4 mol l À1 ) to reduce memory effects and washing-out time. Matrix interference effects due to the presence of the base in the spray chamber were compensated by using the standard additions method.…”

Sensitive determination of bromine and iodine in aqueous and biological samples by electrothermal vaporization inductively coupled plasma mass spectrometry using tetramethylammonium hydroxide as a chemical modifier

“…Inductively coupled plasma atomic emission spectrometry (ICP‐AES) has advantages over these techniques and it provides satisfactory stability, a wide calibration range and robustness. ICP mass spectrometry (MS) has also been used for the determination of total iodine concentration due to its high sensitivity and selectivity 16–19. For iodine speciation, some specific iodine‐containing species have been successfully determined by liquid chromatography coupled with ICP‐MS 20–23.…”

Sensitive determination of iodine by tungsten boat furnace vaporization with inductively coupled plasma mass spectrometry using tetramethylammonium hydroxide as a chemical modifier

“…5,6 Due to its high sensitivity and selectivity, ICP mass spectrometry (MS) is also used for the determination of total iodine species. [7][8][9] Regarding iodine speciation, some of the specific species containing iodine have been successfully determined by hyphenated methods such as liquid chromatography coupled with ICP-MS 10,11 and capillary electrophoresis coupled with ICP-MS. 12 In ICP-MS, aqueous sample solution is often introduced via a nebulizer. However, this introduction method allows only small amounts of the nebulized solution to actually reach the ICP.…”
