The Specific Activity Calculator accepts an input volume, activity, specific activity for a given isotope and calculates the amount of isotope present in the sample both in moles and moles/volume.
Access the Specific Activity Calculator by going to NucMed > Apect. Act. Calculator.
The Specific Activity Calculator requires several values to make its calculations. An activity, volume, isotope, and specific activity are used to calculate the number of excited molecules and molarity of a given sample.
μCi and measurement time.
|Amount of isotope as measured in a dosimeter or with the NanoSPECT.
|The volume containing the activity.
|The isotope of interest and its associated half-life. Several pre-defined options are available.
kBq/pmol and measurement time.
|The specific activity of the isotope being used as measured by a specific activity calibration. Specific activity describes the number of excited atoms out of the total atoms present in a given sample, i.e., the amount of the activity that has not yet decayed to a ground state.
|The calculated amount, or number, of excited molecules in the sample.
|The calculated molarity, or concentration, of excited molecules in a sample of activity.
