Remarks on result:
other: Flowrate 12 ml/h. Mean of 10 samples. CV=6.8%.
Details on results:
The coefficient of variation (n= 10) was ≤ 30% at both flow rates. It demonstrated that the system was equilibrated at all flow rates.

The maximum difference on the mean values at both flow rates was ≤ 30% (0.54% was calculated). The water solubility of the substance is given as the mean value of these measurements: 0.0453 mg/L.

No test substance was detected in the samples from the blank column.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The column elution method was performed, resulting in a water solubility of 0.0453 mg/L. The study was performed in accordance with EC A.6, OECD 105 and EPA OPPTS 830.7840 guidelines and according to the principles of GLP.
