Du plomb dans les jouets ? Un contrôle s’impose.
Une grande partie des jouets vendus sur les marchés américains et européens est fabriquée en Chine. Or ceux-ci connaissent de vives critiques en ce qui concerne la qualité au vu de la présence de matières potentiellement dangereuses, susceptibles d’aboutir à des actions de rappel et réclamations de dommages et intérêts onéreuses. Plus les cas signalés sont nombreux, plus les consommateurs hésitent à acheter des articles venus de Chine, ce qui justifie donc un contrôle sans failles dans l’intérêt des fabricants. Depuis l’entrée en vigueur de la directive européenne RoHS (Restriction of Hazardous Substances), la limitation de l’utilisation dans les biens de consommation de substances telles le plomb, le cadmium ou le mercure, est clairement réglementée.
Analysis of cadmium in plastics
In recent years, mass media have focused on the topics of the environment and environmental conservation. With the advancement in scientific technology, resource development has progressed.
Bigger is not Better
There is a trend towards smaller samples that have more controlled particle size and yet remain representative of the material being analyzed.
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....
Cryogenic preparation of sample materials
Within the context of sample preparation, size reduction plays an important role as it has a substantial influence on the results of the subsequent analysis. If the particles are too coarse or inhomogeneous the results of the analysis may turn out to be incorrect, especially if there is only a very small amount of sample material which represents the total amount.
Los especial del pigmento
Debido a la ilimitada variedad de colores y texturas que ofrencen los recubrimientos en polvo; muchos de los nuevos recubrimientosde aplicación especifica se crean en el laboratorio en pequeñas cantidades que luego se le envían al cliente para su aplicación y aprobación.
Molienda ultrarrápida y ultrafina
El nuevo molino ultracentrífugo ZM 200 de RETSCH es un molino de rotor no sólo extremadamente rápido y cuidadoso con el material molido, sino también de uso universal gracias a su amplia gama de accesorios.
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.
Reliable sample preparation in food technology
An efficient sample preparation procedure for rapid, reliable and reproducible analytical results is becoming increasingly important today. Ever more stringent requirements are being set both in research and production, e.g. for product monitoring and quality control.
Sample Preparation of Plastics for X-Ray-Fluorescence Analysis
The elemental analysis of plastics has become more and more important. EC directive 91/338/EWG regulates the ban of cadmium in PVC, EC directive 94/62/EC defines limits for cadmium, lead, chromium and mercury in packing materials and EC directive 2000/53/EC defines limits for the same elements in end-of-life vehicles. This has created a strong need for a rapid and reliable testing method.
Sample Preparation of Solid Materials for the XRF-analysis
X-Ray fluorescence is one of the most versatile methods to determine elements in a sample. The material is exposed to x-rays that cause each element to emit its own unique fluorescent x-ray. The subsequent analysis of the results is based on comparisons to standard samples with given chemical composition.

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 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.
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.
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.
Zerkleinern von Proben in einem Düngemittellabor
Für die genaue und reproduzierbare Analyse von Düngernährstoff, Spurennährstoffen und Spurenmineralien ist das vorherige Zerkleinern der Probe unverzichtbar. Das Düngerlabor der Division of Regulatory Services der University of Kentucky verwendet zum Homogenisieren der Proben die Ultra-Zentrifugalmühle ZM 200 von Retsch.
Zuverlässige Probenaufbereitung in der Lebensmitteltechnologie
Eine effiziente Probenaufbereitung für schnelle, zuverlässige und reproduzierbare Analyseergebnisse wird in der heutigen Zeit immer wichtiger. Sowohl in der Forschung, als auch in der Produktion, z. B. bei der Produktüberwachung und Qualitätskontrolle, werden immer strengere Maßstäbe gesetzt.
