RoHS Calibration Standards for XRF

RoHS Data storage, PANalytical

RoHS Calibration Standards aid manufacturers and research laboratories comply with requirements of RoHS II legislation. Developed in co-operation with DSM Resolve, they provide the accurate calibration required for precise determination of product compliance using X-ray fluorescence (XRF) spectrometry.

Benefits of RoHS Calibration Standards

The RoHS Calibration Standards guarantee the highest levels of analytical accuracy and precision over a wide concentration range of elemental determination - from low ppm to low percentage. They offer unrivalled homogeneity and are the closest, in respect of composition, to official EU BCR 681k and 680k Certified Reference Materials. This enables compliance with confidence.

Ideal for use with several polymer types, including PolyPropylene (PP), PolyEthylene (PE) and others, the RoHS Calibration Standards extend PANalytical’s range of innovative industry solutions designed to meet environmental legislation challenges such as RoHS II, WEEE and ELV.

The standards consist of PE discs containing chemicals, representing the elements and compounds regulated by RoHS II:

  • Mercury (Hg), lead (Pb), cadmium (Cd)
  • Bromine (Br) and chromium (Cr) - representing brominated flame-retardants and hexavalent chromium (CrVI+)

Six additional elements commonly present in polyolefins as additives or fillers are also incorporated in the standards:

  • Arsenic (As)
  • Chlorine (Cl)
  • Antimony (Sb)
  • Tin (Sn)
  • Zinc (Zn) and
  • Sulfur (S)

A unique property of PANalytical’s RoHS solutions is the carefully selected uncorrelated concentrations for all elements that enable accurate determination of line overlap correction factors. The ultimate benefit is improved accuracy.

The RoHS Calibration Standards contain four different multi-element standards with different concentrations and a blank in four replicates. These five materials (four reference materials plus one blank) in quadruple make a total of 20 discs.

Alternatively, an economic RoHS Calibrations Standards basic package can be ordered. This basic package contains two replicates of all multi-element standards, each incorporating four reference materials plus blank material in duplex, making a total of ten discs.

The perfect combination, Epsilon 4 for screening and quantification

Polymeric compliance is important and requires that no restricted substances are present in materials. Aiming for restricted substance levels in polymers that just comply, can go wrong when materials are combined because the cumulative quantities can be higher than accepted limits.

Epsilon 4, with best-in-class performance, is ideal for low-level screening and quantification at low mg/kg (ppm)-levels.
