Shimadzu Total Support for EU WEEE/RoHS & ELV Directive Compliance
Analyses of hazardous metals and substances
Shimadzu offers a range of instruments and application supports for the analyses of the hazardous metals and substances controlled by the European Union WEEE/RoHS and ELV directives.
In accordance with the EU (European Union) Directives on Waste Electrical and Electronic Equipment (WEEE) and Restriction of Hazardous Substances in Electrical and Electronic Equipment (RoHS), from July of 2006, electrical products exported to Europe must not contain any of the specified hazardous metals, namely, cadmium, lead, mercury, and hexavalent chromium, or the specified hazardous substances, namely, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE).
In accordance with the European Parliament and European Council's Directive on End-of-Life Vehicles (ELV), the concentrations of specified hazardous metals (i.e., cadmium, lead, mercury, and hexavalent chromium) must be below certain levels.
The use of parts and materials free of hazardous substances, as exemplified by green procurement, has become an important issue in commercial transactions. There are corporations that have established their own criteria and demand analysis reports from suppliers of materials such as plastic and resin parts used in electrical and electronic equipment.
Shimadzu helps customers comply with these regulations by providing them with the required analytical and measuring instruments and application techniques.
Hazardous Metals: Cd, Pb, and Hg
Screening Applications
These spectrometers enable the simple, rapid analysis of resins, metals, oxides, and liquids at the ppm level without pretreatment. The μEDX, which uses Shimadzu's unique polycapillary (patent approved), is capable of measuring diameters as small as 50 um, that is difficult to attain with other X-ray fluorescence spectrometers.
EDX-700HS
Energy Dispersive X-ray Fluorescence Spectrometer
μEDX-1200
Energy Dispersive X-ray Fluorescence Spectrometer
High-precision Quantitative Applications
Simply dissolving the sample is all that is required to perform high-sensitivity measurements of toxic metals, regardless of the sample's type or history. Measurement is possible not only of toxic metals that were added intentionally, but also of toxic metals contained within substances as impurities. Furthermore, the Sequential Plasma Emission Spectrometer and Inductively Coupled Plasma Mass Spectrometer can perform the batch analysis of several toxic metals.
ICPS-7510
Sequential Plasma Emission Spectrometer
ICPM-8500
Inductively Coupled Plasma Mass Spectrometer
AA-6300
Atomic Absorption Spectrophotometer
Hazardous Metal: Hexavalent Chromium
Hexavalent-chromium Selective-analysis Applications
UVmini-1240
UV-VIS Spectrophotometer
After hexavalent chromium is extracted from the sample at the pretreatment stage using, for example, boiling water, the extract is measured with the UVmini-1240 and Water-quality Measurement Program Pack using diphenylcarbazide absorption photometry, and the amount of hexavalent chromium is obtained. (See note.)
Note: Although extraction using, for example, boiling water is necessary for measuring the hexavalent chromium (e.g., in screws), the total amount of hexavalent chromium cannot be extracted in this way. The concentration obtained with diphenylcarbazide absorption photometry does not necessarily reflect the total amount of hexavalent chromium contained in the sample.
Hazardous Substances: Brominated Flame Retardants
Screening Applications
Fourier Transform Infrared Spectrophotometer -IRPrestige-21
Using a single-reflection ATR accessory and a bromine flame retardant identification macro program enables the identification of plastics and brominated flame retardants in a matter of tens of seconds. The lower detection limit is of the order of a few percent (concentration) and so this method is used in screening applications.
High-precision Quantitative Applications
Gas Chromatograph Mass Spectrometer - GCMS-QP2010 Plus
The constituents of brominated flame retardants are separated with a gas chromatograph and detected with a mass spectrometer. This makes it possible to analyze brominated flame retardants with a high degree of precision. In order to ensure high accuracy, however, samples must be treated beforehand to remove resins or other substances that may obstruct analysis.
