XRF calibration

Improved XRF calibration reference materials

Crocker researchers have developed improved certified reference materials for calibration, calibration verification and QC of XRF analyzers utilized for analysis of airborne particulate matter (PM) samples.

Our system can provide pure, stoichiometric reference materials on various filter materials (and different filter sizes) and is useful for any air pollution sampling projects that collect PM on filters for analysis by XRF. Having calibration standards prepared on the same filter material as PM samples collected in the field mimics the filter matrix effects of the samples and thus provides a more reliable calibration.
