Description
|
SRM 2703 - Sediment for Solid Sampling (Small, Sample) Analytical TechniquesStandard Reference Material (SRM) 2703 is a marine sediment collected at the mouth of the Baltimore Harbor. SRM 2703 is primarily intended for use in evaluating analytical methods for the direct determination of selected elements in solid samples of marine or fresh water sediment and similar matrices. Direct and slurry sampling, as well as dissolution techniques using typically milligram size samples (<10 mg), can employ this SRM in the user’s procedures; all certified and reference values are based on measurements using a samples size of at least 0.7 mg. Techniques using large samples (100 mg) should use SRM 2702 Inorganics in Marine Sediment. All of the constituents for which certified, reference, and information values are provided in SRM 2703 were naturally present in the sediment material before processing. keywords: direct solid sample analysis , environmental material , soil/sediment , trace elements , heavy metals |
