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....
Tracking down hazardous substances (RoHS/WEEE)
Preparing electronic waste for obtaining representative analytical samples.
A solution for converting an electrical appliance into a meaningful analytical sample is described using a remote-controlled toy car as an example.
Size reduction within the context of sample preparation
In general “size reduction” is taken to mean the disintegration of solid substances by mechanical forces without altering their state.

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.
The Representative Sample Preparation of Waste
Now that a certain environmental awareness has developed in the population over the past few years, our efforts are geared not only to avoiding waste, but also to reducing the mountains of waste which still arise by means of raw material recovery and the reintroduction of secondary raw materials into the industrial cycle.
Probenvorbereitung gemäß RoHS und WEEE
Die neuen europäischen Richtlinien 2003/108/EG (WEEE) und 2002/95/EG (RoHS) regeln die Entsorgung von Elektround Elektronik-Altgeräten sowie die Beschränkung bestimmter gefährlicher Stoffe in Elektro- und Elektronikgeräten. In Deutschland wurden diese Richtlinien im Elektro- und Elektronikgerätegesetz (ElektroG) umgesetzt, welches am 24. März 2005 in Kraft getreten ist.
Recycling: Aufbereitung von Elektronikschrott
Vor dem Hintergrund der neuen EU-Richtlinien zur Entsorgung von Elektro- und Elektronik-Altgeräten sowie der Richtlinie zur Beschränkung bestimmter Schwermetalle und bromierter Flammschutzmittel, stellt sich für Verwerter und Entsorger von Elektronikschrott sowie Hersteller neuer Elektrogeräte die Aufgabe, entsprechend festgelegte Nachweisgrenzen analytisch zu erfassen.
Vom Netzkabel zur Analysenprobe
Seit August 2004 gelten neue EU-Richtlinien zur Entsorgung von Elektro- und Elektronik-Altgeräten sowie zur Beschränkung bestimmter gefährlicher Stoffe in diesen Geräten, welche die EU-Mitgliedsstaaten in nationales Recht umsetzen müssen.Diese Richtlinien haben auch Auswirkungen auf Analyselabors.
