Determination of Major Electrolytes, Minor Minerals, and Trace Heavy Metals in Physiological Fluids by Flame and Graphite Furnace Atomic Absorption Spectroscopy
14 Jan 2013Accurate measurement of specific metals in various biological systems is extremely important. These metals can be classified into several groups including high level major electrolytes, minor minerals, trace heavy metals, or toxics. The latter elements are either known to be detrimental to the body, or have a currently unknown activity that is purported to be harmful. Therefore there is a need for an analytical system to be able to differentiate and quantitate these elements easily and reproducibly. This application note, demonstrates the Buck 210VGP Atomic Absorption Spectrophotometer is the most economical instrument for this work.

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.
