23 Conclusion The Agilent 5100 ICP-OES with synchronous vertical dual view meet the requirements outlined in the US EPA method 6010C. SVDV means only one reading of the samples which gives high sample throughput and quicker sample measurement leading to considerable gas savings of only 20 L of Ar per sample. SRM samples were analyzed on SVDV and good recoveries (92-107%) were achieved for all elements. Ionization interferences was eliminated using SVDV with radial view plasma leading to wide dynamic range for EIE elements. Excellent Long term stability is achieved as no moving optical part in SVDV instrument Exceptional MDL s, linearity for all elements Confidentiality Label July 2,
