Analytical radiochemistry tool based on a linear calibration curve y = mx + b
Peak area is below the calibration baseline.
The peak area (y) must be greater than the intercept (c) for a valid mass calculation.
Slope cannot be zero.
A zero slope causes division by zero in the mass calculation.
Calculated Mass
x = (y − b) / m

Injected Radioactivity
A = Conc (mCi/mL) × Vol (µL) / 1000

Specific Activity (Mass)
SA = A / x

Specific Activity (Mass)
SA (mCi/mg) = SA (mCi/µg) × 1000
