The Analysis of Water and Wastes by U.S. EPA Method 200.7 Using the Optima 8300 ICP-OES and prepFAST Auto-Dilution/Calibration System
24 Oct 2013U.S. EPA Method 200.7 Version 4.4 covers the use of inductively coupled plasma optical emission spectroscopy (ICP-OES) in radial and/or axial viewing for the determination of metals and some non-metals in water and wastes for regulatory compliance. This application note describes the completion of U.S. EPA Method 200.7 using the PerkinElmer® Optima® 8300 ICP-OES coupled with the prepFAST™ Automated In-Line Auto-Dilution/Calibration System.

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.

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.Waste WaterWater AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).
