This standard block combines all the glasses in standard blocks REE6G and REE16G.

These glasses have been developed to replace the fluorides and pure metals traditionally used as standards for REE analysis.

REE glasses have the advantage of providing a standard which is easily polished, free from surface oxidation and generally lowers the magnitude of the analysis ZAF correction. Typical area of each glass after polishing is approximately 4 mm²

All the above glasses can be supplied as a set or supplied individually in customer specified standard blocks. These glass standards have all been chemically analysed in duplicate and the glasses are issued with a certificate of analysis from a NAMAS certified laboratory. They have all been tested for homogeneity by EPMA.
