Performing an Alpha Beta Assay
The following tasks are required when performing an Alpha Beta Assay.
 Calibrate the Instrument, if necessary.
 Define and Run an Alpha Beta Standards Assay (page 75) to establish the
optimal pulse decay discriminator value.
 Define an alpha beta nuclide in the Alpha Beta Nuclide Library. Choose a
Standards Set (second column in the table) from the Alpha Beta Standards
Library to use the discriminator setting from the Standard Set. If you do not
choose a Standard Set, manually enter a discriminator setting directly in the
Alpha Beta Nuclide Library.
 Open an existing assay or create a new assay by choosing Alpha Beta assay
type. Select the desired alpha beta radionuclide name on the Count
Conditions tab and define the remaining assay parameters
 Save the assay in the Assays folder of the Packard\TriCarb directory.
 Associate (link) the assay parameters with a protocol number in the protocol
tree and attach the corresponding protocol clip to the first cassette to be
counted.
 Load the cassette(s) with vials and load the instrument with cassettes.
 Start the instrument.
