A capillary electrophoresis-electrospray mass spectrometry (CE-ESI-MS) method for the separation and determination of nine biogenic amines is proposed. Operational variables, such as the voltage, temperature, sheath liquid composition, flow-rate, and MS parameters, were optimized. Samples are injected in the hydrodynamic mode into a 75 cm x 50 microm ID coated capillary and separated by using 25 mM citric acid at pH 2.0. Heptylamine is used as internal standard. The experimental setup includes a flow manifold coupled to the CE system for automatic insertion of samples into the CE vials. The proposed method allows amines to be determined with limits of detection from 0.018 to 0.09 microg x mL(-1) and relative standard deviation (RSD) values from 2.4% to 5.0% (except 6.8% for histamine). The method was successfully used to determine biogenic amines in red and white wines.
