Guidance of measurement methods and test procedures. Basic tests for polarization-maintaining optical fibres Ingestion-build-82396 for a variety of fibre1 Scope This International Standard specifies two methods for the determination of mercury in drinking, surface, ground, rain and waste water after appropriate pre digestion. For the first method (described in Clause 6), an enrichment step by amalgamation of the Hg on, for example, a gold platinum adsorber is used. For the method given in Clause 7, the enrichment step is omitted. The choice of method depends on the equipment available, the matrix and
