Estimation of the Adsorption Coefficient (Koc) using High Performance Liquid Chromatography (HPLC)

Key value for chemical safety assessment

Additional information

The partition coefficient was determined based on a calibration curve using 7 reference items.Two peaks were determined during the measurement of the test item.The retention time of the test material was determined to be for peak I 4.6 minutes and for peak II 5.5 minutes.

In conclusion the absorption coefficient of the test material was determined to be 2.1 and 2.2 using the HPLC method.
