Water Analysis Following U.S. EPA Method 200.7 Using the Teledyne Leeman Lab’s Prodigy7 ICP-OES
29 Jan 2015In the Safe Drinking Water Act, the EPA outlines National Primary Drinking Water Regulations, which specifies the Maximum Contaminant Levels (MCLs) for drinking water contaminants that are known for causing adverse health effects in people. This application note describes the capability of the Teledyne Leeman Lab’s Prodigy7 ICP-OES for performing analyses of drinking water samples in accordance with USEPA Method 200.7.

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.
