Apparatus and method for affixing thin film material to sample cup used in X-ray spectroscopy
DCFirst Claim
1. An apparatus for mounting a thin-film of material across an open end of a sample cup, said thin film for retaining a sample to be analyzed spectrochemically, said apparatus comprising:
- a substrate having a through hole;
a thin film material bonded to said substrate and covering said through hole, said thin film material having a perforated line of weakness defining said thin film material into an inner region and an outer region, said line of weakness situated within said through hole;
wherein, application of said apparatus over an open end of a sample cup so that said inner region of said thin film material engages the sample cup and extends across the open end thereof causes said inner region to detach from said outer region of said thin film material thereby separating said apparatus from said inner region of said thin film material.

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.

10. A method for mounting a thin film of material across an open end of a sample cup used for retaining a sample to be analyzed spectrochemically, said method comprising the steps of:
-
providing a planar frame member having a through hole and a thin film material bonded thereto so that said thin film material covers said through hole, said thin film material having a perforated line of weakness positioned within said through hole, said perforated line of weakness defining said thin film material into an inner region and an outer region; placing said planar frame member onto an open end of a sample cup of so that said inner region extends across said open end of said sample cup; and simultaneously tautening said inner region of said thin film material and detaching said inner region of said thin film material from said outer region of said thin film material along said perforated line of weakness to separate said planar flame member from said sample cup. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
