ABSTRACT:
A method for covering a sample cup for retaining a sample to be analyzed spectrochemically, the method comprising the steps of attaching a thin-film material to a substrate having a through hole to form a planar frame member, the thin-film material covering the through hole and having a patterned perforation positioned within the through hole defining an inner covering surface with diameter d1 and an outer detaching surface; disposing the planar frame member onto an open top surface of the sample cup with diameter d2 less than d1 such that the inner covering surface of the thin-film material extends across the open top surface; and depressing a portion of the planar frame member to cause detachment of the thin-film material from the substrate along the patterned perforation, and thereby causing increased tautness of the inner covering surface which extends across the open top surface.
