Soil samples collected from key locations from the grounds of a 200 year old building in New England illustrate expected variations in Lead (Pb) content. A DELTA analyzer configured in SmartShot Soil analysis mode was used to analyze the samples. Spectral data is shown using the DELTA PC Software. |

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. Each reading was analyzed for 60 seconds. +/- error shown is 2-sigma, 95% confidence. |
