AA/ICP/OES
Atomic asbortion spectroscopy uses the absorption of light to measure the concentration of gas-phase atoms. Samples are vaporized in a flame and the atoms absorb ultraviolet or visible light and make transitions to higher electronic energy levels. The analyte concentration is determined from the amount of absorption. Flame temperatures of 3000º C are achievable using a gas mixture of acetylene and nitrous oxide. The limitation of atomic absorption spectroscopy is that only one element may be analyzed at a time. Detection limits are element dependent with high ppb levels being common.
Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)
ICP-OES produces excited ions and atoms by ionization in an intense electromagnetic field that emit detectable amounts of light at characteristic wavelengths, with intensities proportional to the concentration of the ion. Argon plasmas reach temperatures up to 10,000 º C during ICP-OES anaylsis. Detection limits of inductively coupled plasma are typically in the low ppb range with the additional feature of analyzing multiple elements simultaneously.
We do much more than ICP -OES and atomic absorpition spectroscopy. The list provided is a general list of methods but we are not limited to the methods. If interested in a method that is not listed, please contact us for further information.
