HPLC method
- Details on study design: HPLC method:
- 8 calibration substances were injected into a HPLC-system under the same analytical conditions (column temperature 40 C) as the test item. A calibration curve was created by using the measured retention times (log K'-values) and the known log Koc-values of the calibration substances for linear regression.
The measured log k'-value of the test item was within the calibrated log k'-range.
From the resulted calibration curve and its equation the log Koc of the substance had been interpolated.

Study title: AE C648993 Adsorption coefficient Koc (HPLC-Method)
The adsorption coefficient (Koc) of AE C648993 was determined according to OECD 121 guideline and EEC-guideline 2001/59/EEC C19. Therefore, 8 calibration substances were injected into a HPLC-system under the same analytical conditions (column temperature 40 C) as the test item. A calibration curve was created by using the measured retention times (log K'-values) and the known log Koc-values of the calibration substances for linear regression.
The measured log k'-value of the test item was within the calibrated log k'-range.
From the resulted calibration curve and its equation the log Koc of the substance had been interpolated.
The adsorption coefficient (koc) of the test item is:
Log Koc = 2.41
Koc = 259
