Publikováno v: Journal of Chromatography A. 838:303-311

We are proposing a novel capillary zone electrophoresis for the simultaneous determination of nitrate and nitrite ions in seawater. An artificial seawater was adopted as the carrier solution to eliminate the interference of high concentrations of chl

Simultaneous determination of tributyltin and triphenyltin cations by capillary isotachophoresis with potential-gradient detector for direct detection

Autor: Kazuo Hiiro, Keiichi Fukushi, Shin-ichi Wakida, Sahori Takeda, Keiitsu Saito, Katsunori Sagishima

Publikováno v: Analytica Chimica Acta. 383:205-211

A capillary isotachophoresis procedure was developed for the determination of tributyltin (TBuT) and triphenyltin (TPhT) cations; 10 mM potassium hydroxide containing 0.1% Triton X-100 and 50% acetone was used as the leading electrolyte. The pH of th

Determination of bromide ions in seawater by capillary zone electrophoresis using diluted artificial seawater as the buffer solution

Autor: Keisuke Watanabe, Shin-ichi Wakida, Kazuo Hiiro, Keiichi Fukushi, Kunishige Higashi, Sahori Takeda, Masataka Yamane

Publikováno v: Journal of Chromatography A. 802:211-217

A novel capillary zone electrophoresis method was developed for the determination of bromide ion in seawater. A tenfold-diluted artificial seawater was adopted as the buffer solution, to prevent interference from high concentrations of chloride ion i

Simultaneous determination of bromide and iodide ions by capillary isotachophoresis using quaternary ammonium salts

Autor: Kazuo Hiiro, Keiichi Fukushi

Publikováno v: Journal of Chromatography A. 760:253-258

Bromide and iodide ions were determined simultaneously by capillary isotachophoresis using an aqueous electrolyte system; the separation principle was based on the ion-pairing equilibria between tetradecyldimethylbenzylammonium ion and these anions i
