di-Lithium tetraborate, Spectromelt® A 100 for XRF (X-ray fluorescence), Supelco®
di-Lithium tetraborate

Spectromelt is based on lithium borates for fluxing digestion as granulate or as fused material used for X-ray fluorescence analysis (XRF).
The fused particles are spherical, have a small particle size distribution and a higher bulk density.
The material is easy to handle and has a low loss on ignition.
