Description

CAS: 13453-69-5 | B4H14Li2O7 | 183.23 g/mol

Used in borate fusion sample preparation of various samples for analysis by XRF, AAS, ICP-MS, ICP-AES and ICP-OES. Used to determine the trace level of elements in contaminated soil. Useful fod dissolving acidic oxides such as SiO2, and Fe2O3. A mixture of lithium metaborate and lithium tetraborate is useful for dissolving most of the inorganic oxides to enable spectrochemical analysis.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
