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 2016

Standard 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 Corporation

  Featuring 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.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples. Find the best atomic absorption, photoelectron and optical emission spectrometers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.EPA MethodsEPA methods are procedures approved by the U.S. Environmental Protection Agency for monitoring and analyzing environmental pollutants, including air, water, and soil samples. These methods are critical in ensuring public health and environmental safety.
