Název v původním jazyce

A miniaturized analyzer for the catalytic determination of iodide in seawater and pharmaceutical samples

Popis výsledku v původním jazyce

A monolithic flow conduit was especially designed and coupled to a multisyringe unit (MSFIA) in order to develop a kinetic analytical method. The new device, denoted CHIP, integrates different functions in a reduced size including confluent mixing, reaction coil, and thermostating, which allowed minimizing the dimensions of the entire analyzer system. The CHIP-MSFIA was satisfactorily applied to the determination of iodide using the Sandell-Kolthoff reaction. The resulting system allows fast, simple andautomatic analysis in seawater samples and a pharmaceutical preparation. By the use of an additional syringe, reagent blank, sample blank, unspecific interferences, and sample analyte concentration was evaluated by simply changing the mode of operation.The instrumentation and analytical procedures were optimized in respect of sensitivity. A limit of detection of 4.7 mu g L-1 and linear working range of 4.3-70 mu g L-1 were achieved. Two new modes of air bubble elimination were develope
