High Throughput, Low Cost Analysis of Environmental Samples According to US EPA 6010C Using the Agilent 5100 SVDV ICP-OES
A routine method for the analysis of major, minor and trace elements in a certified channel sludge reference material according to EPA method 6010C is described. Excellent recoveries were obtained for the 31 elements analyzed using an ICP-OES operating in synchronous dual view mode. A switching valve system was used to achieve a sample-to-sample analysis time of 60 seconds and argon consumption of 19 L per sample.
