ABSTRACT:
The invention relates to a device and a method for mass-spectrometric analysis of substance samples which have been separated by capillary electrophoresis, particularly proteins, proteoglycanes or other protein conjugates, with ionization of the substance samples by a particularly substance-saving form of electrospraying. A method of "microspraying" is used which permits a flow of spray liquid of only several tens of nanoliters per minute in stable spray operation. The invention consists in a loose coupling of the spray capillary to the electrophoresis capillary in a liquid environment.
