Prep your XRF samples with Spectromelt® for higher accuracy
There are two principal techniques used for sample preparation in X-ray fluorescence (XRF) analysis, making a flux or pressing the sample into tablet form. High purity Spectromelt® borates are ideal for fluxing digestion where a high degree of precision is needed. Spectromelt® grinding aids are optimized for automated sample preparation where speed is essential.
- Formulations available for both fluxing and grinding techniques
- Homogenous samples for precise analysis
- Optimized for automated sample preparation
- High purity – trace impurities identified for optimal instrument adjustment
Fusion for high sample homogeneity
Fusion with high purity Spectromelt® borate fluxes results in very homogenous samples. Extensive quality specifications ensure all Spectromelt® fluxes contain negligible trace impurities and have a high batch-to-batch consistency. This reduces the need for instrument adjustments and increases accuracy. Spectromelt® A-series, based on lithium borate, and B-series, based on sodium borate, are available as powder or fused particles. The high-density fused particles are spherical with a small particle size making them easier to handle.
Robust tablets for automated sample preparation
Tabletting the sample is an alternative to fusion. The Spectromelt® C-series is optimized for grinding and tabletting. The robust nature makes it perfect for use in automated sample preparation where speed of analysis is essential.
Two types of Spectromelt® C tablets are offered. Samples prepared with Spectromelt® C10 are very stable for analysis and storage due to its adhesive properties. While ,Spectomelt® C20, which is less hygroscopic, is ideal for use in damp conditions.

| * = Spectromelt® fused quality During the production process of the Spectromelt® the material is molten to achieve high-density particles. The particles are spherical and have a small particle size distribution. The fused material has a higher density than the granulated material. The advantage for the end-user is that the fused material is easier to handle in the laboratory and has a lower loss on ignition. |
