Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 238 words
A combination package and template including a thin-layer chromatographic plate, the plate having a perimeter of prescribed length and including a thin layer of chromatographic adsorbent, said combination comprising: a backing member including a front surface having a perimeter of a length greater than the length of the perimeter of the plate to be packaged, said front surface having a first portion corresponding in area and configuration to the area and configuration of the plate to be packaged and at least one second portion forming a marginal area between the first portion and at least a portion of the perimeter of the front surface of the backing member; indicia located in said marginal area for denoting locations on the adsorbent layer of the plate to be packaged; means on the backing member for positively locating the plate upon the first portion of the front surface of the backing member in a predetermined position with respect to said indicia and for securing the plate in said predetermined position against movement relative to the backing member in all directions parallel to the front surface of the backing member; and a film of pliable plastic material overlying the first and second portions of said front surface and removably affixed to the backing member when the plate is in said predetermined position upon the backing member for removably retaining the plate in said predetermined position between the film and the backing member.
Claim 2
Dependent Claim 238 words
A combination package and template including a thin-layer chromatographic plate, the plate having a perimeter of prescribed length and including a thin layer of chromatographic adsorbent, said combination comprising: a backing member including a front surface having a perimeter of a length greater than the length of the perimeter of the plate to be packaged, said front surface having a first portion corresponding in area and configuration to the area and configuration of the plate to be packaged and at least one second portion forming a marginal area between the first portion and at least a portion of the perimeter of the front surface of the backing member; indicia located in said marginal area for denoting locations on the adsorbent layer of the plate to be packaged; means on the backing member for positively locating the plate upon the first portion of the front surface of the backing member in a predetermined position with respect to said indicia and for securing the plate in said predetermined position against movement relative to the backing member in all directions parallel to the front surface of the backing member; and a film of pliable plastic material overlying the first and second portions of said front surface and removably affixed to the backing member when the plate is in said predetermined position upon the backing member for removably retaining the plate in said predetermined position between the film and the backing member.
Claim 3
Dependent Claim 71 words
The combination of claim 1 wherein said means for positively locating and securing the plate includes a recess in the front surface of the backing member, said first portion being recessed relative to said second portion of the front surface and said second portion extending around the entire perimeter of the first portion of the front surface such that the perimeter of the recess corresponds to the perimeter of the plate.
Claim 4
Dependent Claim 64 words
The combination of claim 2 wherein the film is removably adhered to the second portion of the front surface of the backing member around the entire perimeter of the first portion thereof such that the plate will be sealed in the package around the entire perimeter of the plate when the plate is in said predetermined position between the film and the backing member.
Claim 5
Dependent Claim 65 words
The combination of claim 1 wherein: the plate is rectangular and includes opposite sides and opposiTe ends; the first portion of the front surface of the backing member has corresponding opposite sides and opposite ends; the marginal area is juxtaposed with at least one side of said first portion; and the indicia include a migration gauge juxtaposed with said one side of the first portion.
Claim 6
Dependent Claim 38 words
The combination of claim 4 wherein said means for positively locating the plate includes a recess in the front surface of the backing member, said first portion being recessed relative to said second portion of the front surface.
Claim 7
Dependent Claim 65 words
The combination of claim 1 wherein: the plate is rectangular and includes opposite sides and opposite ends; the first portion of the front surface of the backing member has corresponding opposite sides and opposite ends; the marginal area is juxtaposed with at least one end of said first portion; and the indicia include a spotting guide juxtaposed with said one end of said first portion.
Claim 8
Dependent Claim 38 words
The combination of claim 6 wherein said means for positively locating the plate includes a recess in the front surface of the backing member, said first portion being recessed relative to said second portion of the front surface.
Claim 9
Dependent Claim 81 words
The combination of claim 1 wherein: the plate is rectangular and includes opposite sides and opposite ends; the first portion of the front surface of the backing member has corresponding opposite sides and opposite ends; the marginal area is juxtaposed with at least one side and one end of said first portion; and the indicia include a migration gauge juxtaposed with said one side of the first portion and a spotting guide juxtaposed with said one end of the first portion.
Claim 10
Dependent Claim 71 words
The combination of claim 8 wherein said means for positively locating and securing the plate includes a recess in the front surface of the backing member, said first portion being recessed relative to said second portion of the front surface and said second portion extending around the entire perimeter of the first portion of the front surface such that the perimeter of the recess corresponds to the perimeter of the plate.
Claim 11
Dependent Claim 64 words
The combination of claim 9 wherein the film is removably adhered to the second portion of the front surface of the backing member around the entire perimeter of the first portion thereof such that the plate will be sealed in the package around the entire perimeter of the plate when the plate is in said predetermined position between the film and the backing member.
