Comparing Field Portable X-Ray Fluorescence (XRF) To Laboraotry Analysis Of Heavy Metals In Soil

摘要

Field portable x-ray fluorescence (XRF) continues to gain acceptance as a com plement to traditional laboraotry testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditiosn, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a laboratory for confirmatory analysis. This confirmatory analysis can provide valuable information of the effectiveness of the field methodology.
