PREPARATION AND CHARACTERIZATION OF DRIED-RESIDUE CALIBRATION STANDARDS FOR USE IN MICROSAMPLE X-RAY ANALYSIS (MXA)
Microsample X-ray Analysis (MXA) is one of the most sensitive XRI? methods using conventional energy-dispersive or wavelength-dispersive spectrometers. Detection limits in the parts-per-billion areExpand
DEVELOPMENT OF AN AUTOMATED SAMPLE PREPARATION STATION FOR MICROSAMPLE X-RAY ANALYSIS (MXA)
In Microsample X-ray Analysis (MXA), a droplet of sample-typically 50 microliters-is evaporated onto a thin film sample support substrate and the resulting residue is analyzed for trace elements. InExpand
