ABSTRACT:
A method for evaporating solvent in a manner that lessens the chance of cross-contamination between samples. The method involves the use of a filter material press fit into solvent-containing sample tubes. The material allows the flow through of evaporation while substantially preventing the flow through or loss of analyte. The method is particularly suitable for use in evaporative procedures involving vacuum, blow-down, and/or centrifugal processes.
