Cement - representative sample preparation is important To produce high-quality cement, the mineralogical and chemical composition of raw materials as well as intermediate and finished products has to be determined. At each stage of the production, samples have to be taken, processed and analysed to ensure quality control without gaps. Retsch offers a range of instruments that are used for sample preparation during the complete production process, from the quarrying of the raw materials to the final product. The typical sample preparation process involves preliminary size reduction, sample division and fine size reduction before the sample can be submitted to further analyses....
Feststoffproben - kein Problem! Wer Mischungen aus organischen und anorganischen Proben analysieren muss, kennt das Problem: Während sich Sand, Lehm oder Steine mit geeigneten Labormühlen meist homogen zerkleinern lassen, führt der hohe Energieeintrag bei organischen Bestandteilen wie Stärke oder fett zu hartnäckig festsitzenden Verbackungen.
The preparation of samples of solid substances for spectroscopic analysis X-ray fluorescence spectrometry is one of the most versatile multi-element methods of chemical analysis. The technique is based on excitation of fluorescent radiation from a sample by bombarding it with high energy X-ray quanta and subsequent study of the characteristic X-ray radiation emitted by its elements.
