Figure 4.
RUBY-FILL® test elution results (n = 6 each). At each elution flow-rate, the dose-calibrator maximum activity (A) is a constant fraction (slope) of the integrated total QA activity. The corresponding ratios of Dose-calibrator Maximum/Integrated Total calibration activity (B) are extrapolated to the value of 0.761 that would be expected using a 50 mL @50 mL·min−1 elution. Standard deviation error bars (~ 1%) are smaller than the plotted symbol size
