Analytical Conditions and Separation Performance of Capillary Chromatography Based on the Tube Radial Distribution of Aqueous–Organic Mixture Carrier Solvents under Laminar-Flow Conditions
Analytical Conditions Separation Performance Capillary Chromatography Based
2010/9/14
We have developed a capillary chromatography system using an open capillary tube made of fused-silica, polyethylene, or poly(tetrafluoroethylene), and a water–hydrophilic–hydrophobic organic mixture c...
Separation/Determination of Flavonoids and Ascorbic Acid in Rat Serum and Excrement by Capillary Electrophoresis with Electrochemical Detection
Flavonoids Ascorbic Acid in Rat Serum Excrement Capillary Electrophoresis with Electrochemical Detection
2010/9/20
A capillary electrophoresis with electrochemical detection was developed for the simultaneous determination of three flavonoids (naringenin, rutin, quercetin) and ascorbic acid. It was found that nari...
Separation of Inorganic Anions on a Pyridine Stationary Phase in Ion Chromatography
Separation of Inorganic Anions Pyridine Ion Chromatography
2010/9/20
The retention behavior of inorganic anions on a pyridine stationary phase commercially available for hydrophilic interaction chromatography was examined in ion chromatography. Inorganic anions were re...
