Separation of inorganic phosphorus-containing anions by capillary electrophoresis

Simultaneous and rapid determination of added phosphorus(V) compounds in meat samples by capillary isotachophoresis

“…The linear polyphosphates were detected using separation system which included: Cl À and b-alanine, creatinine, or histidine at pH 4, 5, or 6, respectively, whereas glutamic acid solution was the terminating electrolyte (Wang & Li, 1999). Authors found optimum pH range from 4.0 to 5.0 for the separation of the four phosphates, however, linear, cyclic, and lower phosphorus oxoacids (max 4 P atoms) were separated at pH 5.5 with a LE: 0.01 M HCl, histidine and 0.1% Triton X-100 and TE: 0.01 M hexanoic acid.…”

“…Nowadays, electromigration methods, such as: capillary electrophoresis CE and capillary isotachophoresis CITP have been tested as a complementary methods to IC in the analysis of phosphates (Arneth, Herold, & Hammer, 2002;Blatný & Kvasni cka, 1999;Chang, Tseng, Mallipattu, & Chang, 2005;Dušek, Kvasni cka, Lukášková, & Krátka, 2003;Kaniansky, Masár, Marák, & Bodor, 1999;Kvasni cka, 2000;Stover, 1999;Wang & Li, 1999).…”

Determination of total phosphorus in soya food samples by capillary isotachophoresis (cITP)

“…Therefore the level of this element in food should be determined with a precise, fast and simple method. Different analytical methods were applied for phosphorus determination in food samples [12][13][14][15][16][17], among others based on electrophoresis (capillary electrophoresis and capillary isotachophoresis) [18,19].…”

“…The analysis of phosphates in various matrices performed with a capillary isotachophoresis method (cITP) was reported in many reviews [1][2][3]11,19]. Phosphates were analysed in cereal grains, legumes and feed mixtures [20], in commercial feed additives [21] and in tobacco [22].…”

Capillary electrophoretic determination of phosphate based on the formation of a Keggin-type [PMo12O40]3− complex

“…Several methods have been developed for the determination of P(V), including conventional colorimetry based on the formation of mixed-valence heteropoly blues (COL) [1], ion chromatography (IC) [2,3], flow injection analysis (FIA) [4], and capillary electrophoresis (CE) [5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Recently, CE has shown to be a powerful technique for the analysis of P(V), in which the most common detection mode is indirect UV detection using suitable absorbing anions such as chromate [19].…”
