Agilent Matrix Modifiers for Graphite Furnace AA

Chemical modifiers are used in graphite furnace atomic absorption spectrometry (GFAAS) to change the thermochemical behavior of both the analyte and the sample matrix. Modifiers may be used both to stabilize the analyte, thus allowing higher ash temperatures, and to move the atomic signal away from the background signal, allowing more accurate background correction. Chemical interferences can also be reduced by using higher atomization temperatures.

Using the right modifier, or mix of modifiers, can simplify an analytical method and improve accuracy, precision, sensitivity, and quantification limits. Agilent offers a comprehensive range of modifiers for use with graphite furnace atomic absorption spectrometry. And with the assurance of NIST traceability, Agilent's selection of standard mixes offers accurate, reliable calibrations at great value.
