Quantitative determination of methylamines using microelectrodes.
A new method for measuring methylamino compounds such as choline, trimethylamine, trimethylamine-N-oxide, betaine, L-carnitine, and dimethylamine is described. A glass microelectrode is used to quantify methylamines in concentrations ranging from 0.1 to 10.0 mM. Rapid time response and a good sensitivity are maintained by the microelectrode even when measurements are performed in solutions having high ionic strength and low pH. These characteristics make this assay suitable for use with conventional column chromatographic techniques of separation for these methylamines.
