Nguyen, Vo Thanh Phuong published the artcileUrine iodide determination by ion-pair reversed-phase high performance liquid chromatography and pulsed amperometric detection, COA of Formula: C11H9I3N2O4, the main research area is urine iodide ion pair reversed phase HPLC pulsed amperometry.
A sensitive and specific ion-pair reversed-phase HPLC method for urinary iodine anal. is described. This method is based on pulsed amperometric detection (PAD) using a silver working electrode (HPLC-PAD), which improves peak shape, electrode stability as well as linearity and reproducibility. A two-step extraction process consisting of solid phase extraction (SPE) and liquid-liquid extraction with dichloromethane was added to improve sample purification which is essential using PAD. Treated samples were eluted on a C18 column, using a phosphate buffer containing ion-pairing reagent tetrabutylammonium and 5% MeOH. The calibration standard curves were linear up to 500 μg/L and within-run and between-run coefficients of variation (CVs) were <6% with the quantification limit fixed at 6 μg/L. Accuracy, expressed as recovery, ranged from 94% to 104%. Comparison with the Technicon Automated analyzer acid digestion (AA) method resulted in a high correlation (r = 0.9916). Due to a low quantification limit and high sample throughput, the proposed technique appears suitable for both epidemiol. and clin. follow-up studies. Talanta published new progress about Homo sapiens. 117-96-4 belongs to class isoquinoline, name is Diatrizoic Acid, and the molecular formula is C11H9I3N2O4, COA of Formula: C11H9I3N2O4.
