Spectromelt® A 1000 Li₂B₄O₇ + 0,.07% LiBr für XRF (Röntgenfluoreszenz), Supelco®
di-Lithiumtetraborat
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.
- Extensive specification of trace impurities
- Batch-to-batch consistency
- High purity materials
