L’avancée des matières premières biogènes
Particularités de la préparation des plantes
Les métaux lourds dans les jouets
Du broyage à l’analyse
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.
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....
Cutting Mill SM 300 - Refinement of a well-proven grinding principle
Cutting mills are used in many different areas of sample preparation for subsequent analyses. Typical applications include the size reduction of secondary fuels, the processing of biomass for renewable energy research, the control of products in the context of RoHS and WEEE regulations or the recovery of precious metals – the variety of sample materials is huge.
Detection of Mycotoxins in Nuts
Preliminary and fine size reduction
Powerful Cutting Mill
The SM 300 excels especially in the tough jobs where other cutting mills fail. It has a freely selectable speed range from 700 to 3,000 rpm with high torque. The mill is convenient to operate and easy to clean. Reliable and extremely efficient sample preparation in the laboratory is now guaranteed with the SM 300.
Preparación de muestras altamente heterogéneas para el control de calidad
El agotamiento de los recursos y el aumento del precio de los combustibles primarios tales como el petróleo, el gas o el carbón han obligado a la industria del cemento a buscar fuentes alternativas de energía. Otro factor contribuyente es, sin duda, el comercio de emisiones que hace todavía más rentable el cambio a fuentes de energía con un balance neutro de CO2, en su mayoría combustibles no fósiles. En los últimos años, se ha registrado un incremento en el uso de fuentes de energía alternativas, especialmente por aquellas industrias con una alta demanda energética. En consecuencia, viene ganando cada vez más importancia el empleo de combustibles secundarios o alternativos, que en su mayoría son extraídos de residuos urbanos e industriales – es decir, residuos urbanos que no han podido ser recuperados ni reciclados.
Preparation of Elastic Plastics for the Detection of PAH
Polycyclic aromatic hydrocarbons, short PAH, are usually a by-product of combustion and can be found, for example, in cigarette smoke or oil-based products. Mineral oil containing PAH is often used in rubber products as plasticizer, especially in black-coloured products such as car tyres, rubber grips of tools or rubber shoe soles. It was discovered that some polycyclic aromatic hydrocarbons are carcinogenic, so that maximum permissible values have been determined for the concentration of PAH in consumer products.
Sample Preparation of Electronic Scrap in the Context of RoHS and WEEE
Since August 2004 new EU directives for the disposal of used electrical and electronic appliances as well as the restricted use of certain hazardous substances in these devices have become effective.
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.
Sample preparation of electronic scrap with SM 2000 and ZM 200
RETSCH mills in the context of RoHS and WEEE
Size reduction of elastic plastics with volatile components
Neutral-to-analysis sample preparation for the detection of PAH and phthalates
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.

  • Ensayos en “preformas” de PET para seguridad del consumidor

    El formaldehído es un producto químico utilizado ampliamente en la producción industrial de materiales como plásticos, en el procesado de telas o en la preservación de materiales biológicos. Sin embargo, el formaldehído es también considerado por muchas normas como peligroso para la salud. Puede provocar reacciones alérgicas y ha sido clasificado como cancerígeno en 2004. Según la norma alemana Oeko-Tex 100, la ropa para niños no debe contener concentraciones de esa sustancia superiores a 20 PPM.
