A capillary electrophoresis method has been developed for the analysis
of melatonin, which depends on whether tryptamine and serotonin must
be determined as well. If only a melatonin analysis is required, a bar
e capillary with a pH 4.41 buffer separates the analyte from the other
two compounds, which are unresolved. If determination of all three sp
ecies is necessary, a bare capillary with a pH 2.14 buffer is used. Fo
r better resolution of tryptamine and serotonin without the analysis o
f melatonin, a chemically modified capillary surface that lowers the e
lectroosmotic now is necessary.
