Handheld XRF (x-ray fluorescence) is a powerful, non-destructive technique that can identify and quantify multiple elements simultaneously. The instrument has a wide range of applications including metal identification, determination of the presence of lead, soil analysis, coating analysis, and stain analysis. XRF works by emitting an x-ray beam capable of displacing electrons in the inner … Continue reading Handheld XRF Analysis for Identification of Stains, Lead Paint, Zinc Primer, Galvanizing, and Aluminum Substrate

Case Study: Staining of Exterior Marble Tile Caused by Cold Applied Asphaltic Waterproofing Membrane: Solved by FTIR Analysis
In 2013, marble tiles were installed as pedestrian pavers on the exterior plaza of a new condominium built near the Atlantic coast in Florida. After three years of being in service, the marble tiles started exhibiting orangish brown surface staining that had a similar appearance to iron oxide staining. Replacement of the marble tiles would … Continue reading Case Study: Staining of Exterior Marble Tile Caused by Cold Applied Asphaltic Waterproofing Membrane: Solved by FTIR Analysis
