- Temp.:
- 25 °C
- pH:
- 6
- Details on results:
- The three calibration series and three Test Item series were measured alternately. The partition coefficient Pow was determined based on a calibration curve using 6 reference substances. The capacity factors k was calculated from the dead time and retention times of the reference substances. The log k data of the reference substances were plotted against their log Pow values. The equation of the curve fitted to the calibration points is as follows:
log k = 0.373 × log Pow - 0.732 (Rsq = 0.975) - Conclusions:
- The calculated logk is in the range of 0.522-0.788 the logPow: 3.36-4.07.
- Executive summary:
The calculated logk is in the range of 0.522-0.788 the logPow: 3.36-4.07.
