Abstract
An integrated liquid sample handling system for matrix-assisted laser-desorption/ionization time-of-flight mass spectroscopy (MALDI-TF MS) is described. The integrated system comprises a miniaturized sample handling compartment containing a MALDI ionization surface for separating, chemically manipulating and detecting analytes by MALDI -TOF MS. The miniaturized integrated sample handling system disclosed herein is applicable to a wide range of analytical problems that require separation and/or chemical manipulation of a sample prior to mass analysis as part of the analytical procedure.
