Validation
The linearity of the detector response with respect to concentration was assessed over relevant concentration ranges for each matrix analyzed during the determination of partition coefficient. In each case, the results were satisfactory with a first order correlation coefficient of at least 0.9997 being obtained. The results are summarized in the following table:

Recovery of analysis of the aqueous phase sample extraction procedure was assessed and proved adequate for the test. At a nominal fortified concentration of 0.10 mg/L, a mean percentage recovery of 96.1 % was obtained (n = 5, range 92.6 to 99.8%, RSD = 3.2%). Reported aqueous phase concentrations have not been corrected for the mean percentage procedural recovery.
Discussion
The solubility of the test item in n-octanol was confirmed to be greater than a nominal concentration of 30 g/L. Therefore, the nominal stock solution concentration of 18 g/L satisfied the guideline requirements of being below 70% saturation concentration in n-octanol and below 0.1 M.
In the absence of any relevant dissociating functional groups, no specific manipulation of the aqueous phase pH was required to ensure that the test item was present in an unionized form. Therefore the determination was performed at an approximately neutral pH.
