Abstract

Abstract

The invention relates to a system and method for on-line coupling of liquid capillary separation with matrix-assisted laser desorption ionization mass spectrometric analysis. In this system and method, analyte from liquid capillary separation is mixed with matrix molecules for matrix-assisted laser desorption ionization. Continuous flow of the analyte/matrix combined with vacuum conditions allows evaporation and crystallization of homogeneous samples on a solid sample surface. Dual use of laser irradiation to desorb/ionize and remove excess sample facilitates on-line use and automation.
