Test solutions
- Details on test solutions:
- Identity and concentration of auxiliary solvent for dispersal: Preparation of test solutions started with a stock solution
of 100 mg/l applying 30 minutes of magnetic stirring. For
the range-finding test the resulting dispersion was filtered
through a paper filter Schleicher and Schuell 604, (ca. 5
um). For both the limit test and the final test the
resulting dispersions were filtered through a glass fibre
pre-filter (Schleicher and Schuell GF 92) to remove the
larger undissolved test substance particles and subsequently
through a membrane filter (Schleicher and Schuell RC55,
0.45um). The lower test concentrations for the range-finding
test and the final test were prepared by subsequent
dilutions of the filtrate in test medium. The final test
solutions were all clear and colourless.
