* below the lowest calibration level (0.528 µg/L)

The water solubility at flow rates of 6.25 mL/h and 12.5 mL/h yielded values below the lowest calibration level (< 0.528 µg/L) at the concentration plateau of five successive fractions. As an exception fraction 7 at a flow rate of 6.25 mL/h yielded 11.66 µg/L.

The WS was determined at 20 °C. The pH value of the collected aqueous fractions was 6.3.
