Technical Details

The use of an XRF instrument to take measurements is a unique process, where additional information is sometimes helpful in creating a better understanding of the measurements and the process involved in realizing these measurements. Below is a group of documents that help to explain some of the technical details involved when using an XRF instrument to measure the amount of lead in paint.

PPM vs mg/cm2
This document explains the differences between measuring the amount of lead in Parts Per Million (PPM), as commonly done by a lab, compared to Milligrams per Centimeter Squared as done with and XRF instrument.

Negative Readings
It is common for an XRF instrument to display negative readings (i.e. -0.1 mg/cm2.) This document describes why this can occur.
