Abstract
Field-portable X-ray fluorescence (FPXRF) spectrometers have been successfully used for on-site rapid characterization of hazardous metallic waste sites. The Outokumpu Electronics, Inc. (OEI), X-MET 880 and the Spectrace Instruments, Inc., Spectrace model 9000 FPXRF spectrometers' ability to analyze filters used in monitoring air quality was evaluated. The instruments differ in their energy resolving power and calibration methodology. Both instruments, representing two different analytical techniques, performed similarly. Typical method detection and quantitation limits, results of an accuracy check, conformational laboratory chemical analysis and results of a blind performance evaluation are presented.
