Interface Device And Process To Couple Planar Electrophoresis With Spectroscopic Methods Of Detection

Abstract

An introduction means for the direct introduction of a sample taken from a planar electrophoresis into an interface to a mass spectrometer utilizing laser desorption ionization. The introduction means includes a probe to collect a sample from a planar electrophoresis, generally a gel electrophoresis, comprising a dual electrode assembly and a potential gradient between the electrodes to collect the sample. Alternatively, the sample is obtained from a freeze-squeeze method or a drying/matrix-deposition method.
