Sample Priostat
This method allows you to count individual samples using a number of different
analysis options without the need for defining an assay. It is a high priority
interrupt mode, operating similarly to Group Priostat. Note: The Sample Priostat
feature is not available on the 2800 series instrument. It is an optional feature on
the 2900 series instrument.
The following items are available via the Run-Sample Priostat menu option:
„
Decay allows you to assess the duration of luminescence in a radioactive
sample via a decay histogram.
„
SPC Decay allows you to assess the duration of luminescence in a non-
radioactive, luminescent sample via a decay histogram.
„
Identify Nuclide allows you to identify an unknown nuclide in your sample
using the Quench Indicating Parameters SIS and tSIE.
„
Optimize Regions allows you to optimize sample counting regions to provide
the highest figure of merit in Normal count mode for samples with constant
quench.
„
Reverse Region allows you to optimize sample counting region settings for a
sample and determine the equivalent unquenched region settings for variable
quench samples.
„
Low Level Optimize allows you to optimize sample counting regions to
provide the highest figure of merit for Low Level count mode.
„
Alpha Beta Preview allows you to view the sample spectrum and approximate
the activity for a sample containing both an Alpha and a Beta emitting
nuclide.
„
Normal Preview allows you to view the sample spectrum and approximate the
activity for a sample using Normal count mode.
„
Low Level Preview allows you to view the sample spectrum and approximate
the activity for a sample using Low Level count mode.
Sample Priostat is a manual process; you must select Count from the Run menu
to initiate sample counting. To move to the next sample in the cassette, you must
select Next Sample from the Run menu. To stop the counting of a sample, you
must select Stop from the Run menu. To end the Sample Priostat counting
session, you must select End Sample Priostat from the Run menu.
The data that is generated during any of the Sample Priostat options are not
saved. You can print the data by selecting the print button in the Report window.
