Alpha Beta Nuclide Library (not available on the 2800TR)
You can use the Alpha Beta Nuclides Library to define and save Alpha and Beta
nuclide names, their associated counting regions, the instrument’s discriminator
setting (this allows discrimination between alpha and beta events). Using the
Standard Set button located in (column 2) of this library, you can reference
parameters established for an existing Standard Set.
Figure 6-2 Alpha Beta Nuclide Library Window.
Name
This is the name given to the alpha beta nuclide. To type in a new name click on
the ADD button. This will create an additional row to define a new nuclide. Type in
the desired name to be used in an alpha beta assay.
Standard Set
This is the name of the Alpha Beta Standard set that will be linked (associated)
with the Alpha Beta Nuclide name. Clicking on this field displays the entire Alpha
Beta Standards library. In the Alpha Beta Standards Library, highlight the desired
standard set you wish to link to the nuclide and press OK. That name will now
appear next to the Alpha Beta Nuclide name.
Beta A:LL
This is the lower limit of the counting region for the Beta nuclide in Region A, in
keV.
Note:This value cannot exceed 2000
