Sinossi
Excerpt from Standard Reference Materials: Methods and Procedures Used at the National Bureau of Standards to Prepare, Analyze and Certify Srm 2694, Simulated Rainwater, and Recommendations for Use
The pressing need of the scientific community for a common reference material for rainwater and the desire by us to field test such a material led to the production and distribution of a Research Material, RM 8409, Simulated Rainwater. Rms are distinguished from srms according to the definitions of the Office of Standard Reference Materials, National Bureau of Standards, In brief, rms are high quality materials whose composition have been established by a single technique for each component. The composition of srms is certified after much more extensive testing involving at least two independent techniques for each component, or analysis by a definitive met hod. Often an RM uncovers unforeseen problems, as was the Situation in this case. This problem involved the long-term stability of the ammonium ion.
The extent of the instability and its ramifications will be addressed below.
