Dead time: t0 = 1.01 min
Calibration data 1st injection::
Regression: log Pow = a + b log k
Parameters: a = 2.558, b = 2.778, r^2 = 0.9812
tR = 18.31 min
k = 17.1
log k = 1.23
log Pow = 6.0
Calibration data 2nd injection::
Regression: log Pow = a + b log k
Parameters: a = 2.552, b = 2.786, r^2 = 0.9809
tR = 18.29 min
k = 17.1
log k = 1.23
log Pow = 6.0
mean log Pow of the test substance = 6.0
log Pow =6.0 - Conclusions:
- The log Pow of the test was found to be 6.0.
- Executive summary:
The log POWof the sample was tested according to EU Method A.8 and OECD Guideline 117 in a non-GLP study at 25 °C and at a pH of 6.0.
It was found to be log POW= 6.0.
