Conclusions:
The three results obtained do not differ from each other as required by the standard, so that a solubility can be declared for the Lincol OHS <1 ppm.
Executive summary:

The Flask Method (according to Regulation N. 440/2008) was applied to 25 ppm Solution of Lincol OHS.The three results obtained do not differ from each other as required by the standard, so that a solubility can be declared for the Lincol OHS <1 ppm.
