## Abstract Several acidic xylooligosaccharides containing unsaturated “hexenuronic acid” units, i.e. 4‐deoxy‐L‐threo‐hex‐4‐enopyranosy‐lurinic acid (4‐ΔU) units, were separated as their alditol derivatives by capillary zone electrophoriesis in 438 mM borate buffer (pH 10.3) and were detected selec
Capillary zone electrophoresis (CE) under conditions of reversed polarity is used in conjunction with electrochemical detection (EC) at carbon fiber microcylinder electrodes for the selective and sensitive determination of uric acid in human blood serum. Comigration of anions with the electroosmotic
