| General / Calibration | 0.5 – 1.0 g | Tungsten or LECOCEL II |
Intended Applications
These crucibles are specifically designed for high-temperature combustion analysis in carbon and sulfur (C/S) elemental determinators. Primary uses include:
- Quality control and certification of steels, irons, and metal alloys
- Analysis of ores, minerals, and mining samples
- Testing of cements, slags, catalysts, and other inorganic materials
- Metallurgical, materials science, and industrial laboratory workflows requiring reliable low-level carbon and sulfur quantification
The exceptionally low blank values make them particularly valuable for samples with trace or ultra-low carbon/sulfur content.
