Process for ionizing analysis materials on the tips of micro dendrites under the influence of a high electric field, comprises feeding the materials to the tips of the dendrites

摘要

Process for ionizing analysis materials on the tips of micro dendrites under the influence of a high electric field comprises feeding the materials to the tips of the dendrites as a component of a liquid matrix which is temporarily vacuum-resistant in the ion source and has a high surface mobility. An Independent claim is also included for a device for ionizing analysis materials on the tips of micro dendrites comprising micro dendrites (2) with microtips (3) connected to a sample feed tube (1) either directly and/or at a distance of a few millimeters. Preferred Features: The micro dendrites are connected directly to the outlet opening (4) of the sample tube.
