RoHS/ELV Directives - Measurement of Heavy Metals Using ICP-MS Application
نویسندگان
چکیده
This application note describes a robust analytical method for the determination of heavy metals and 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.

Comparison of the Levels of Five Heavy Metals in Human Urine and Sweat after Strenuous Exercise by ICP-MS
Inductively coupled plasma mass spectrometry (ICP-MS) was used to measure the levels of trace heavy metals in human urine and sweat, to compare the performance of ICP-MS using three sample processing methods, namely direct dilution, wet digestion, and microwave digestion. The results showed that the wet digestion ICP-MS method has the highest accuracy (relative standard deviation ≤10%) and is m...

This application note describes the quantification of cadmium, chromium, lead and mercury in plastic materials by external calibration using the Agilent 7500ce ICP-MS system equipped with an Octopole Reaction System (ORS). Isotope dilution analysis with ICP-MS was used as a confirmatory technique. Good agreement of the results obtained by the two calibration approaches was achieved. The sample ...
متن کاملAnalytical Methods for the Determination of Heavy Metals in the Textile Industry
Heavy metals in textile wastewater represent a major environmental problem, and are a potential danger to human health when present on textiles. Furthermore, the presence of some metals influences the production of textiles. Heavy metals are often used as oxidizing agents, as metal complex dyes, dye stripping agents, fastness improvers, and finishers. Thus, they act as hazardous sources through...
