Analysis of Highly Mineralized Aqueous Solutions by ICP-AES, a Non-Dilution Method with Multi-Wavelength Calibration for Major, Minor and Trace Elements
Analysis of Highly Mineralized Aqueous Solutions by ICP-AES, a Non-Dilution Method with Multi-Wavelength Calibration for Major, Minor and Trace Elements
17 May 2016Standard EPA methods using Inductively Coupled Plasma (ICP) expect that samples will be fairly dilute without an overabundance of dissolved constituents. However, geochemical samples with more than 2000ppm dissolved solids may give incorrect results when running methods as written. This application note demonstrates an analysis method that uses low-sensitivity analytical lines for the high-concentration major components and high-sensitivity analytical lines for the low-concentration trace components. This eliminates the need for multiple dilutions to get major elements on-scale.

ICPE-9800 Series: Simultaneous ICP Emission Spectrometers
Shimadzu CorporationFeaturing user-friendly software and a proprietary design, the simultaneous ICPE-9800 series instruments enable sensitive, high-speed simultaneous analysis of multiple elements regardless of concentration levels while significantly reducing operating costs. Key features include a vertically oriented plasma torch with dual view (axial/radial) capabilities that achieves the ideal combination of sensitivity and dynamic range, and a leading-edge CCD (charge-coupled device) detector with one million pixels. Eco Mode and a mini-torch system significantly minimize argon gas consumption, resulting in substantial cost savings. Easy-to-use, 21 CFR compliant software helps users optimize methods and enables a smooth analysis process. The Assistant functions help users optimize methods by automatically acquiring wavelength data, selecting optimal wavelengths, diagnosing methods and providing inter-element correction for an all-around smooth analysis process. In addition to the standard accessories, additional torches, chambers, nebulizers, drains and other parts are available for the ICPE-9800 series so users can customize their systems for their specific application needs.
