Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
245 words
A method for assaying radioactivity of a sample of a liquid, using a liquid scintillation counter having a standard sample container wherein the standard sample container has a standard outer cross-section and defines an interior space having a standard volume, including a standard interior height and a standard interior width, the sample of the liquid being tested having a relatively small volume less than the standard volume, the method comprising placing the relatively small sample in a sample inner container, the sample inner container having an outer crosssection and defining an interior space having a height at least equal to the standard interior height and a width less than the standard interior width; removably inserting the sample inner container into an adapter holder formed of a clear, transparent material, the adapter holder comprising a longitudinally extending side wall defining an inner cross-section and an outer cross-section, the outer cross-section being substantially congruent to the standard outer cross-section and the inner cross-section of the adapter holder being larger than the outer cross-section of the inner container, but providing a relatively close fitting relationship along at least a portion of the longitudinally extending sidewall of the adapter holder so as to center the sample inner container within the adapter holder; whereby when the adapter holder, including the sample inner container inserted therewithin, is placed into the scintillation counter, the scintillation counter can accurately assay the radioactivity of the relatively small sample contained within the sample inner container.
Claim 2
Independent Claim
245 words
A method for assaying radioactivity of a sample of a liquid, using a liquid scintillation counter having a standard sample container wherein the standard sample container has a standard outer cross-section and defines an interior space having a standard volume, including a standard interior height and a standard interior width, the sample of the liquid being tested having a relatively small volume less than the standard volume, the method comprising placing the relatively small sample in a sample inner container, the sample inner container having an outer crosssection and defining an interior space having a height at least equal to the standard interior height and a width less than the standard interior width; removably inserting the sample inner container into an adapter holder formed of a clear, transparent material, the adapter holder comprising a longitudinally extending side wall defining an inner cross-section and an outer cross-section, the outer cross-section being substantially congruent to the standard outer cross-section and the inner cross-section of the adapter holder being larger than the outer cross-section of the inner container, but providing a relatively close fitting relationship along at least a portion of the longitudinally extending sidewall of the adapter holder so as to center the sample inner container within the adapter holder; whereby when the adapter holder, including the sample inner container inserted therewithin, is placed into the scintillation counter, the scintillation counter can accurately assay the radioactivity of the relatively small sample contained within the sample inner container.
Claim 3
Dependent Claim
219 words
In combination with liquid scintillation counter comprising a holder portion for a standard container, the liquid scintillation counter being designed to measure the radioactivity of a standard volume sample contained within a standard container, having a standard outer cross-section and defining a standard interior space having a standard interior height and a standard interior width: a device for permitting the assaying of the radioactivity of a relatively small sample of liquid, having a volume less than the standard volume, the device comprising an adapter holder having a longitudinally extending side wall formed of a transparent material and defining an outer holder cross-section and an inner holder cross-section, the outer holder cross-section being substantially congruent to the standard outer cross-section; and a sample inner container formed of a transparent material and removably held within the adapter holder, the adapter holder and the inner container having a relatively snug fitting relationship alOng at least a portion of the side wall of the adapter holder so as to center the inner container within the adapter holder, the sample inner container defining an interior space having a standard interior height and a width less than the standard interior width, whereby the sample inner container can be completely filled using a sample of less than the standard volume but of the full standard height.
Claim 4
Dependent Claim
219 words
In combination with liquid scintillation counter comprising a holder portion for a standard container, the liquid scintillation counter being designed to measure the radioactivity of a standard volume sample contained within a standard container, having a standard outer cross-section and defining a standard interior space having a standard interior height and a standard interior width: a device for permitting the assaying of the radioactivity of a relatively small sample of liquid, having a volume less than the standard volume, the device comprising an adapter holder having a longitudinally extending side wall formed of a transparent material and defining an outer holder cross-section and an inner holder cross-section, the outer holder cross-section being substantially congruent to the standard outer cross-section; and a sample inner container formed of a transparent material and removably held within the adapter holder, the adapter holder and the inner container having a relatively snug fitting relationship alOng at least a portion of the side wall of the adapter holder so as to center the inner container within the adapter holder, the sample inner container defining an interior space having a standard interior height and a width less than the standard interior width, whereby the sample inner container can be completely filled using a sample of less than the standard volume but of the full standard height.
Claim 5
Dependent Claim
32 words
The combination of claim 2 wherein the standard outer cross-section is circular and the sample inner container is a substantially cylindrical tube, concentric with the outer cross-section, but having a smaller diameter.
Claim 6
Dependent Claim
21 words
The device of claim 3, wherein the sample inner container extends beyond the longitudinally extending side walls of the adapter holder.
