Lead Analysis Using NIST Standards


A DELTA handheld XRF analyzer, configured in SmartShot Soil analysis mode, was used to measure Lead (Pb) in four NIST soil matrix standards and a blank. As shown below, analysis spectra can be easily overlaid and compared using the Delta PC Software. Here the user has zoomed in on the Pb La and Lb peaks for direct comparison.

Data Results

 

Analysis results for the NIST standards are shown at right.

A 60 second measurement time was used.

Results shown in ppm.

+/- error shown is 2-sigma, 95% confidence.

NIST Std Pb Value Given Pb Value Measured +/- Measured
SiO2 Blank 0 <2 -
NIST 2702 132.8 135 4
NIST 2709 18.9 20.2 1.9
NIST 2710 5525 5587 39

Data sample results

 

A reference sample spiked with approximately 500ppm Pb (sample 408) was used for these repeat readings.

Each reading was analyzed for 60 seconds.

+/- error shown is 2-sigma, 95% confidence.
