  • RoHS & WEEE compliance: analysis of polyvinyl chloride (PVC) and acrylonitrile-butadiene styrene (ABS) polymers

    XRF has emerged as an optimal solution for the screening of toxic heavy metals regulated by the EU Directives, RoHS and WEEE. PANalytical's MiniPal 4 RoHS WEEE – an energy-dispersive X-ray fluorescence spectrometer – provides a RoHS/WEEE screening function of the restricted elements. This datasheet describes a straightforward, robust method for the analysis of RoHS elements in two very different ...

  • Analysis of trace hydrocarbon impurities in 1,3-Butadiene using optimized RT-Alumina BOND/MAPD plot columns

    Abstract Identifying and quantifying trace impurities in 1,3-butadiene is critical in producing high quality synthetic rubber products. Standard analytical methods employ alumina PLOT columns which yield good resolution for low molecular weight hydrocarbons, but suffer from irreproducibility and poor sensitivity for polar hydrocarbons. In this study, Rt-Alumina BOND/MAPD PLOT columns were ...

  • Feedstock recycling from plastic and thermoset fractions of used computers (I): pyrolysis

    The increasing production of computers, the progress in their performance, and the shorter time between innovation and production has led to increasing numbers of obsolete products. It has thus become necessary to recover some materials from old computers and to protect the environment from a new type of pollution. Such recycling is difficult because of the diversity of polymeric materials used, ...

  • US EPA airmOzone TESTS

    The US EPA leads Photochemical Assessment Monitoring Stations programs (PAMS) for more than 15 years and many equipments used at PAMS sites are old and need to be replaced. That is why US EPA has conducted a material review of fully automatic GC units able to by analyze the 56 VOC ozone precursors of the PAMS list. They planned to perform an evaluation in two steps : - Laboratory evaluation of ...
