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.
L'analizzatore XRF portatile DELTA per le analisi ambientali permette di controllare in qualche secondo i livelli pericolosamente elevati di RCRA, degli inquinanti prioritari e dei metalli pericolosi. L'analizzatore portatile XRF viene usato per l'analisi dei suoli e dei sedimenti in base all'EPA 6200 e altri SOP, dei filtri in base ai metodi NIOSH o OSHA, delle superfici e dei tamponi per il Pb, Cd, Cr, As, Hg ed altri elementi.
Il DELTA Professional dotato di un rilevatore SDD e un tubo a raggi X ottimizzato da 4 W, assicura performance superiori per la velocità, i limiti di rilevamento o lo spettro elementare. Permette l'analisi del Mg e degli elementi a maggior numero atomico nelle leghe e nei minerali. Il DELTA Professional rappresenta la soluzione Olympus a maggior valore aggiunto per gli analizzatori XRF.
