ABSTRACT:
A chemically inert, non-absorptive applicator sheet, a depression defined by a recessed portion of the applicator sheet, a transfer coating on at least a portion of a top surface of the applicator sheet, means for evaporating a solution of sample and carrier solvent deposited on the transfer coating, and a displacement mechanism for displacing a sample formed in the recess are disclosed. The depression in the applicator sheet may be formed by imposing a suction beneath the applicator sheet; and a displacement of a sample formed in the depression may be accomplished by introducing pressure beneath the applicator sheet.
