Lead Guard The Lead Guard is comparable to the industry-leading Import Guard except it is calibrated only for lead (Pb), rather than the standard 20+ elements. Many import testing problems are focusing on lead-containing paints, making the Lead Guard a more economical solution. And, customers that purchase the Lead Guard may upgrade to the full element capability (20+ elements) of the Import Guard at any later date, at only a little more cost than the price difference. Features: - Analyzes lead in paint in units of mass/area (mg/cm2) for paint layers on base material (substrate) - Limit of detection < 0.01 mg/ cm2 - Software converts from mg/cm2 to ppm if operator provides data on paint thickness and density - Add on bulk sample analysis for direct ppm analysis of bulk samples - X-ray tube-based system eliminates costly resourcing, and regulatory baggage of isotope control - No isotope licensing or travel restrictions - Ergonomic, lightweight design Proven X-ray Tube Technology! The algorithm and software behind the Lead Guard yields the only tube-based XRF to receive an EPA Performance Characteristic Sheet. This means this XRF is the only non-isotope lead paint analyzer to meet EPA and HUD requirements for the testing of lead in paint in residential settings.
