TL;DR
An XRF analyzer is the handheld X-ray fluorescence instrument a certified lead inspector aims at painted surfaces to measure lead content in milligrams per square centimeter, reading through every paint layer down to the substrate without disturbing any of it. Results compare against the federal action threshold, historically 1.0 mg/cm2 with HUD moving to more protective levels, to classify each tested surface as positive or negative for lead-based paint.
What it means
An XRF analyzer is the handheld X-ray fluorescence instrument a certified lead inspector aims at painted surfaces to measure lead content in milligrams per square centimeter, reading through every paint layer down to the substrate without disturbing any of it. Results compare against the federal action threshold, historically 1.0 mg/cm2 with HUD moving to more protective levels, to classify each tested surface as positive or negative for lead-based paint. It is the backbone of pre-renovation lead inspections and abatement clearance work because it tests a surface in seconds where lab chip sampling takes days and leaves damage.
