RoHS Calibration Standards

RoHS Calibration Standards, coupled with a benchtop or laboratory-screening instrument, offer a complete solution for the requirements of RoHS legislation. Developed in co-operation with DSM Resolve, they provide the accurate calibration required for precise determination of product compliance using XRF spectrometry.

Ideal for use with olefinic and other polymers, the RoHS Calibration Standards extend PANalytical’s range of innovative industry solutions for meeting the challenges of environmental legislation such as RoHS, WEEE and ELV.

Multiple benefits

The RoHS Calibration Standards guarantee the highest levels of accuracy and precision over a wide concentration range - from low ppm to low percentage. They offer unrivaled homogeneity and are the closest, in respect of composition, to official EU standards. Furthermore, carefully selected uncorrelated elemental concentrations allow accurate determination of line overlap correction factors.

Determination of all RoHS elements

The standards consist of polyethylene discs containing the elements and compounds regulated by RoHS:

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

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)

The RoHs Calibration Standards contain four different multi-element standards with different concentrations and four replicates. In addition four blanc discs are provided.

Exact and easy-to-use

The standards enable calibration of measured XRF intensities against accurate and precisely determined chemical concentrations. From this calibration, unknown polymer samples can be determined with the highest accuracy and precision.

RoHS Calibration Standards are ideal for use with PANalytical's MiniPal 4, Epsilon 5 and Axios spectrometers.
