Additional information

The test details the determination of the ratio of the equilibrium concentrations of a dissolved substance in a two phase system consisting of two largely immiscible solvents, using high performance liquid chromatography (HPLC) apparatus, the method was carried out in accordance with the procedure stated in OECD Guidelines 123. There were no deviations from the stated method.
