Application Notes

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.

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
NIST 2711	1162	1158	11

A DELTA handheld XRF analyzer, configured in SmartShot soil analysis mode, was used to run repeat measurements on a reference soil sample, to demonstrate repeatability. As shown below, the DELTA PC Software can be used to overlay spectra from different readings for direct comparison and analysis.

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

Each reading was analyzed for 60 seconds.

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

Sample Run	Pb ppm Value	+/-
1	511	7
2	512	7
3	514	7
4	521	7
5	514	7
AVG	514	7

Products used for this application

DELTA Handgerät für die Röntgenfluoreszenzanalyse für Umweltsicherheit

Die DELTA Handgeräte zur Röntgenfluoreszenzanalyse (RFA) prüfen gefährlich hohe Pegel der wichtigsten Schadstoffe und gesundheitsschädlichen Metalle in Sekunden entsprechend RCRA. Sie werden eingesetzt zur Prüfung von Boden- und Sedimentproben nach EPA 6200 und anderen Standardarbeitsanweisungen, zur Analyse von Filtern nach der NIOSH- und OSHA-Methode, und zum Messen des Gehalts an Pb, Cd, Cr, As, Hg und anderen Stoffen an Flächen und in Staubproben.
