Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- 5.1
- Temp.:
- 22 °C
- Remarks on result:
- other: pH not specified
- Details on results:
- The reference substance solutions and the test item solution were injected in duplicate.
Because the retention time of the test item under examination is in the range of the reference substances retention time, the Pow value could be calculated by the linear regression analysis performed using the least squares method.
