Abstract
The present invention is a sample preparation system and method that can be used with all types of analyte materials, that produces homogeneously deposited crystals across a sample surface, and that lends itself to automation. In this system and method, analyte crystallization is caused by lyophilization. A homogeneous analyte/solvent mixture is placed on a sample surface. The mixture is frozen, then the solvent is sublimated through the application of a vacuum. A homogenous distribution of analyte crystals across the sample surface results.
