SD = Standard deviation

1) = Calculation according to formula : Deviation = n(cmax- cmin) x 100/cmin

2) = Calculation according to formula: Deviation = |(c1 -c2)| x 100 / c1

3) = Mean value of two injections; for the third sample at 0.2 mL/min, one injection was eliminated as an outlier

Conclusions:
In the present test the water solubility of Compimide 183 was determined to be 28.3 mg/L (20°C, pH 7) using the Column Elution Method.
