Selected protocol from "Proteins and Proteomics: A Laboratory Manual," Richard J. Simpson.

ABSTRACT
One versatile strategy for sample cleanup prior to MALDI-MS analysis uses microscale columns designed for direct sample elution onto the MALDI target plate. This protocol describes the fabrication of a reversed-phase microcolumn designed for this purpose. The microcolumns are prepared from GELoader tips. This protocol has been optimized for sample cleanup prior to MALDI-MS. However, with slight modifications, it works equally well with samples destined for ESI-MS.
