Spectromelt® A 1000 Li₂B₄O₇ + 0.07% LiBr for XRF (X-ray fluorescence)

Supplier: MilliporeSigma
Synonyms: 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.

  • Extensive specification of trace impurities
  • Batch-to-batch consistency
  • High purity materials
