Determination of Glucose in Submicroliter Samples by CE-LIF Using Precolumn or On-Column Enzymatic Reactions.


Two enzymatic reactions combined with capillary electrophoresis (CE) are used to determine glucose contained in sample volumes of ≤500 nL. In the first enzymatic reaction, glucose is oxidized in the presence of glucose oxidase producing hydrogen peroxide, which reacts quantitatively with the fluorogenic compound homovanillic acid catalyzed by the enzyme… (More)
