How to Perform the SNC (Self-Normalization and Calibration)
SNC for an Instrument without Super Low Level Counting Ability
1. Define the IPA parameters in the IPA Definition window.
Figure 2-1 IPA Definition Window.
2. Reset the SNC protocol flag to the reset position (the flag is all the way to the
left when the plug is on the left end of the cassette).
3. Load the purged, unquenched Carbon-14 standard into the first position of the
cassette (this is at the same end as the protocol plug).
Caution: Do not use the unpurged, Low Level standards to
calibrate the instrument, even if the instrument is to be used in
Low Level, High Sensitivity or Super Low Level count mode.
