3. The analysis of thallium with a mass fraction of thallium 99,98−99,99% is used bidistillated water and reagents qualification not lower than H. h., with a mass fraction of 99.999-of 99.9995% — bidistillated water and high purity reagents brand. In the absence of the latter allowed to use the reagent H. h. after additional purification from impurities determined. All reagents for the determination of silver must be checked for absence of chlorine.

4. When determining the mass fraction of impurities in thallium (with a mass fraction of thallium 99,98−99,99%) is allowed to apply a heat-resistant bowl, in the analysis of thallium (with a mass fraction of thallium 99,999-of 99.9995%) should apply utensils made of quartz glass or fluoroplastic — 4.

5. Determination of impurities in thallium is produced in two parallel batches with simultaneous carrying out two control experiments to make the results of the analysis of the relevant amendment for contamination of reagents.
