This application note describes a robust analytical method for the determination of heavy metals and sub- substances regulated by the EU Restriction of Hazardous Substances/End of Life Vehicles (RoHS/ELV) directives. Based on the experience of Nihon Environmental Services Co., Ltd in Japan using an Agilent Technologies 7500c ORS (Octopole Reaction System) collision/reaction cell ICP-MS, this note summarizes: • An overview and validation of ICP-MS methodology for RoHS applications • Benefits of ICP-MS methodology to the analysis of trace elements in high matrix samples and limitations of EDXRF (Energy Dispersive X-Ray Fluorescence) for the measurement of lead in flame resistant plastics • Advantages of ICP-MS for RoHS applications.

This application note describes a method based on high-performance liquid chromatography (HPLC) coupled to inductively-coupled plasma mass spectrometry (ICP-MS) for the separation and determination of methyl and ethyl mercury. Because the different chemical forms of mercury exhibit different toxicities, separating elemental mercury from the alkylated forms provides vital information on the actual risk posed by a sample. The HPLC-ICP-MS method is applied to the analysis of water and soil samples. The method detection limits in water for MeHg, EtHg, and Hg2+ are better than 10 ng/L, and recoveries between 80% and 120% were obtained for the Hg species extracted from the soil samples.

Agilent PX Scanner is a revolutionary product designed specifically for the identification and X-ray diffraction analysis of protein crystals in situ within multiwell crystallization plates. It is a unique, compact, self-contained unit that combines optical and X-ray imaging. The optical imaging component allows the user to visually locate and select objects, which can then be studied by X-ray diffraction using the built-in microfocus X-ray source, optics, and CCD detector. The 2nd generation Agilent PX Scanner is equipped with a significantly brighter Nova X-ray source and a CCD detector with greatly improved sensitivity. These enhancements make it even more effective at screening protein crystals undisturbed in crystallization plates, saving time by increasing throughput and improving resolution.
