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.

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 (sample 408) was used for these repeat readings.
Os analisadores manuais por XRF DELTA para avaliação ambiental analisa níveis perigosamente altos de RCRA, principais poluentes e metais perigosos em segundos. O analisador manual por XRF é usado para solos e sedimentos ou outros SOP, filtros para métodos NIOSH ou OSHA, rastreamento de superfícies e medir amostras para Pb, Cd, Cr, As, Hg e outros.
Juntamente com o detector de desvio de silício (SDD) e o tubo de raios X de 4W otimizado, o DELTA Professional proporciona desempenho superior em velocidade, limites de detecção e variedade de elementos. Analisa Mg e elementos superiores em ligas e mineração. O DELTA Professional é o analisador manual por XRF com melhor custo-benefício da Olympus.
