With the development of Agilents helium (He) mode Octopole Reaction System (ORS) collision cell and the introduction of High Matrix Introduction (HMI) aerosol dilution technology, robust and accurate ICP-MS analysis of complex high matrix environmental samples such as soils and sludges has become routine [1]. However, increased competition and financial pressure in contract environmental laboratories has led to a greater focus on the productivity of the analytical instruments and methods used. At the same time, it is essential that data quality and ease-of-use are not compromised as sample throughput is increased. To address these more demanding productivity requirements, Agilent has developed a new version of the Integrated Sample Introduction System, ISIS 3, which allows Agilent 7900 ICP-MS users to perform high speed discrete samp领 analysis while maintaining data quality in full compliance with US Environmental Protection Agency (EPA) requirements for data acquisition.
