test mat.

Loading of aqueous phase:

0.122 mg/L

Temp.:

20 °C

pH:

7.3

Details on results:

Preliminary test
The content of test material dissolved in the water sample was 0.122 mg/L.

Main study
The coefficient of variation (CV) (n = 10) was ≤ 30% at both flow rates. It demonstrated that the system was equilibrated at all flow rates.
The maximum difference (MD) on the mean values of the samples at both flow rates was also ≤ 30%. Based on this, the water solubility of the test material is given as the mean value of these measurements.
The turbidity of the eluates was < 0.2 NTU. According to this, no undissolved particles were detected in the eluates.
No test material was detected in the samples from the blank column.
