Urine iodide determination by ion-pair reversed-phase high performance liquid chromatography and pulsed amperometric detection

Physicochemical properties of silica gel coated with a thin layer of polyaniline (PANI) and its application in non-suppressed ion chromatography

“…Limits of detection for investigated anions are comparable to literature data [8,35,39] and the tested stationary phases can be prepared relatively simple and at low costs.…”

“…Special attention was paid for iodide anion because of their biological importance and difficulty in trace analysis caused the high concentration of chloride matrix in environmental and pharmaceutical samples [7,28,34]. Conductivity detection is preferred for anion analysis however obtained LOD value for iodide in this technique are insufficient (about 0.1 ppm) thus spectrophotometric, potentiometric or amperometric detection is recommended for their trace determination [35][36][37]. In our investigations, UV-vis detector was employed for the simultaneous analysis iodide and the other ions in single chromatographic run.…”

Rapid determination of X-ray contrast agent iomeprol in human plasma by on-line solid-phase extraction coupled with phase optimized liquid chromatography

“…However, using the gradient elution technique, signal instability and baseline drift may increase, and an additional re-equilibration time is required [20,21]. Very recently, phase optimized liquid chromatography (POPLC) has been introduced as a new way of selectivity tuning in method optimization [22,23]. The POPLC approach follows a strategy which is based on the optimized combination of column segments with different functionalities.…”

Gold-Nanoparticles-Modified Cellulose Membrane Coupled with Laser Desorption/Ionization Mass Spectrometry for Detection of Iodide in Urine

“…13−23 Earlier reports of iodide determination by ion chromatography using tubular ion-selective electrode show a linear range of 5−400 μg/L and a limit of detection of 1.47 μg/ L. 19 Nguyen et al reported the iodide determination in urine by ion-pair reversed-phase HPLC and pulsed amperometric method with a dynamic range of 20−250 μg/L; however, it is a slightly time-consuming process because of the two pretreatment steps involved. 20 Hu et al used ion chromatography for the determination of fluorine and iodine in urine simultaneously, after decomposition in alkali and pretreatment using an electrochemical oxidation−neutralization device. 21 The inductively coupled plasma mass spectrometry (ICP-MS) technique can detect iodide with good sensitivity but needs an internal standard to reduce matrix effects.…”
