XRF Technology Demonstration Kennedy Space Center, Florida January 24 - 28, 2005
Overview of the Demonstration
The field demonstration of innovative XRF technologies to measure trace elements in soil and sediment began on January 24, 2005, at the Kennedy Athletic, Recreational, and Social (KARS) Park at the Kennedy Space Center on Merritt Island, Florida. The demonstration compared the performance of innovative XRF technologies with conventional analytical methods as employed at an off-site fixed laboratory. These conventional methods include inductively coupled plasma (ICP) atomic emission spectrometry (EPA methods SW-846 6010 and EPA 200.18) and cold vapor atomic absorption (CVAA) spectrometry (EPA methods SW-846 7470 and EPA 245.1). Conventional methods for analysis of trace elements involve extensive sample preparation, using strong acids to digest the sample into solution, and expensive laboratory instrumentation to provide accurate, high-quality data. The innovative XRF technologies evaluated in this demonstration are portable for use in the field or in a mobile laboratory and are capable of providing rapid turnaround of results with minimal sample preparation.
