Frequently Asked Questions
What is ERM-EC681m?
ERM-EC681m is a certified reference material (CRM) produced by the European Commission Joint Research Centre (JRC). It consists of low-density polyethylene (LDPE) granules with certified concentrations of multiple elements commonly evaluated during RoHS and consumer goods compliance testing. It is widely used for quality control, instrument verification, and method validation.
What is ERM-EC681m used for?
ERM-EC681m is primarily used to verify the performance of handheld XRF analyzers during the analysis of plastics and polymers. It is commonly used for:
- Daily instrument verification
- Laboratory quality control
- Method validation
- Analyst training
- Measurement repeatability studies
- Performance monitoring over time
Which handheld XRF analyzers are compatible with this CRM?
ERM-EC681m is compatible with virtually all handheld XRF analyzers designed for plastics, RoHS, and consumer goods applications, including instruments from Thermo Scientific Niton, Evident Vanta, Olympus Delta, Hitachi, Bruker, SciAps, Viken, and many other manufacturers.
Is this reference material certified?
Yes. ERM-EC681m is a certified reference material (CRM) produced by the European Commission Joint Research Centre (JRC). Each unit includes the official certificate listing the certified values, associated uncertainties, and traceability information.
What elements are certified?
ERM-EC681m includes certified values for:
- Arsenic (As)
- Bromine (Br)
- Cadmium (Cd)
- Chlorine (Cl)
- Chromium (Cr)
- Mercury (Hg)
- Lead (Pb)
- Sulfur (S)
- Antimony (Sb)
- Tin (Sn)
- Zinc (Zn)
Can this CRM be used to calibrate a handheld XRF analyzer?
ERM-EC681m is intended primarily for instrument verification, quality control, and method validation rather than factory calibration. Most handheld XRF analyzers are calibrated using proprietary manufacturer calibration procedures. This CRM is ideal for confirming that your instrument continues to perform within expected specifications.
Is this CRM suitable for RoHS compliance testing?
Yes. ERM-EC681m was specifically developed to support laboratories and manufacturers performing RoHS and WEEE screening of plastic materials. It provides certified concentrations of several elements commonly evaluated during compliance testing and is an excellent quality control material for handheld XRF screening.
Does handheld XRF determine the chemical form of bromine or chromium?
No. Handheld XRF measures the total concentration of bromine (Br) and chromium (Cr), but it cannot determine the chemical species or oxidation state. For example, XRF cannot distinguish between restricted and unrestricted brominated compounds, nor can it differentiate hexavalent chromium (Cr(VI)) from trivalent chromium (Cr(III)). Additional laboratory methods are required when chemical speciation is necessary.
Why is bromine included if RoHS restricts specific flame retardants?
Handheld XRF is a screening technology. Measuring total bromine helps identify materials that may contain brominated flame retardants. Elevated bromine levels often indicate that additional laboratory testing may be appropriate to determine whether restricted compounds such as PBBs or PBDEs are present.
What material is ERM-EC681m made from?
ERM-EC681m consists of low-density polyethylene (LDPE) granules. The polymer matrix closely resembles many consumer plastic products, making it well suited for verifying handheld XRF performance on polymer samples.
How often should I verify my handheld XRF with a CRM?
Many laboratories and quality assurance programs perform a verification at the beginning of each workday, after instrument maintenance, following calibration changes, or whenever measurement accuracy needs to be confirmed. The appropriate verification frequency should be established by your organization's quality management system and applicable regulatory or accreditation requirements.
