Reagents for Grinding and Tabletting

Optimized for Automated Sample Preparation

Tabletting the sample is an alternative sample preparation for XRF to fusion. The Spectromelt® C-series is especially developed as a grinding and tabletting aid. In automated sample preparation of powder samples speed of analysis is an important factor. Spectromelt® C10, C15 and C20 are offered as tablets with a weight of 333 mg each. The tablets are robust, so the automated sample preparation will not be disturbed. Tablets made with Spectromelt® C10 are very stable for analysis and storage. Spectromelt® C10 is developed to have distinguishable adhesive properties. Spectromelt® C20 is compared to C10 less hygroscopic because of an adjusted composition. C20 is preferable for damp climate and its properties effect fewer residues in the grinder.

• The new Spectromelt® C15 combines the adhesive properties of C10 and the lower hygroscopy of C20. The improved homogenization of the sample gives more precise results in analysis.
• The new Spectromelt® C15 MP micropowder can be used as a grinding and tabletting aid. Hoechst Wax C can only be used as a tabletting aid.
