Description
|
SRM 612/613 - Trace Elements in Glass These Standard Reference Materials (SRMs) were produced and certified to facilitate the development of chemical methods of analysis for trace elements and are one of a series of four pairs of SRMs. For both SRMs, 612 and 613, the nominal trace element concentration is 50 mg/kg for each of the sixty-one elements that have been added to the glass support matrix. The two SRMs differ only in the thickness of the glass wafer. Units of SRMs 612 and 613 are issued as sets of six wafers. keywords: geological materials , trace elements , heavy metals , direct solid sample analysis
