Atomic Absorption Standards
Matrix Modifiers SPEX CertiPrep® offers a variety of high-purity matrix modifiers for Graphite Furnace Atomic Absorption (GFAA). The matrix modifier will change the behavior of either the analyte element or matrix in solution with respect to temperature, thus allowing a more optimum graphite furnace program to be used. During the pyrolysis stage of GFAA, certain elements are lost due to their high volatility. Matrix modifiers are added to a solution to prevent these losses by converting the element toa less volatile form.
