Screening for Metals by X-Ray Fluorescence Spectrometry Using a Single Calibration Standard
Abstract
Analysis for copper, zinc, arsenic and lead was performed on a variety of solid particle matrices using a portable, high-resolution X-ray fluorescence (XRF) spectrometer. All quantitative determinations were based on an instrumental calibration method that uses a single certified reference material to establish elemental response factors and the Compton K sub alpha peak to normalize for matrix discrepancies. The simple approach to XRF analysis circumvents the need to acquire matrix-matched standards for either empirical coefficients or fundamental parameter methods of calibration. Preliminary results show that response factor/Compton K sub alpha peak normalization is a promising approach when screening for these metals in soils, dust, paint chips and incinerated sludge.
