Comparison of two different approaches to calibrate an energy-dispersive x-ray fluorescence spectrometer for the analysis of aerosol-loaded filters.
The quantitative analysis of aerosol loaded filters by x-ray fluorescence spectroscopy implies the use of calibration curves obtained from synthetic standards. Two preparation methods to obtain these calibration samples are described and compared, showing that matrix and enhancement effects are neglible for membranous filters and that both calibrations lead to acceptable results. Calibration standards produced via an aerosol generator always lead to a greater sensitivity compared to the standard produced with droplets. The filters resist the conditions of replicated measurements.
