RoHS Analyzer for Compliance with Environmental Regulations for Hazardous Substances

Jordan Valley AR, Inc.

Jordan Valley's RoHS Analyzer uses a powerful X-ray tube and a new generation high resolution Si PIN detector (see Table 1) to measure low levels of heavy metals, allowing electronics manufacturers to comply with new regulations designed to reduce environmental waste and adverse health effects.

The Restriction of Hazardous Substances Directive (RoHS), designed to restrict toxic metals in new electrical and electronic equipment, profoundly impacts the electronics industry. Producers must now document the levels of restricted substances in their equipment. RoHS restricts six substances — lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), and certain compounds of bromine (Br), PBB and PBDE. These elements occur in compounds which are commonly used as fillers, stabilizers, pigments, and flame retardants.

To be compliant, manufacturers must prove that these compounds fall below their maximum concentration values (MCV).

Jordan Valley's new RoHS Analyzer was specifically designed to help electronics manufacturers determine the precise level of restricted substances and certify that they fall below the MCV. This high-powered instrument provides fast quantitative analysis of lead in solder for Pb-free electronics requirements, and sorts chlorinated and/or brominated plastics. Highly reliable, accurate analytical results can be obtained in PE, PVC, or other polymers. In one easy step, the analyzer measures extremely low levels of Cr, Hg, Pb, Br, Cd, and other heavy metals and identifies PVC, Br- or Sb- or P-based flame retardants.

The nondestructive energy-dispersive technique means that samples are left unaffected to allow further testing by the same or additional techniques for quality control purposes. Additionally, every step is fully documented with an audit trail for self-certification and compliance verification.

Jordan Valley is a leading designer, manufacturer, and marketer of energy-dispersive X-ray fluorescence (EDXRF) systems and components with more than 30 years' spectroscopic experience. We provide quality and cost-effective answers to real-world analytical challenges by melding the latest technological developments with innovative engineering.
