Concentration and Log P of Each Oligomer Determined at the Last Time Point for the Isopropanol/Water Solutions. Mean and standard deviation values were obtained from three replicate preparations. Log P values preceded by ≤ indicate equilibrium may not have been achieved and thus the final value may be less than that reported. Log P values preceded by ≥ indicate value was less than the QL, and thus the QL concentration was used to approximate the value which may be greater than that reported. ND: Compound was not detected; NA: Not applicable. <QL: Compound was detected, but the response was below the method quantification limit of approximately 0.01 μg/g.
