How To Run an Alpha Beta Assay not available on the 2800TR; optional on the
2900TR and 3100TR series
The following tasks are required when performing an Alpha Beta Assay.
1. Calibrate the Instrument, if necessary.
2. Define and run an Alpha Beta Standards Assay (page 28), if necessary, to
establish the optimal pulse decay discriminator value.
3. Define an alpha beta nuclide in the Alpha Beta Nuclide Library. Choose the
Standards Set from the Alpha Beta Standards Library to use the discriminator
setting from the Standard Set.
4. Create a new assay by choosing Alpha Beta as the assay type. On the Count
Conditions tab, select the desired alpha beta radionuclide name from the Alpha
Beta Nuclide Library. Define the remaining new assay parameters.
Or
Open an existing assay and edit or review if necessary.
5. Save the assay in the Assays folder of the Packard\TriCarb directory.
6. 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.
7. Load the cassette(s) with vials and load the instrument with cassettes.
8. Click the green start button at the top of the main window.
9. Start the instrument.
