Is My Water Corrosive? Is My Water Scale Forming? How Langelier Saturation Index Measures How Aggressive or Scale Forming Water Is

by magroupllc, posted in Building Materials, Corrosion, Forensic Chemistry, Metals, Microscopy, SEM, water

Langelier Saturation Index (LSI) is a calculation that uses the data of multiple analyses to estimate how corrosive or scale-forming a water is. The chemistry of the water is analyzed, as well as the environmental conditions determined, to evaluate how likely the water would be to corrode or form a scale in pipes. LSI is … Continue reading Is My Water Corrosive? Is My Water Scale Forming? How Langelier Saturation Index Measures How Aggressive or Scale Forming Water Is

Handheld XRF Analysis for Identification of Stains, Lead Paint, Zinc Primer, Galvanizing, and Aluminum Substrate

by magroupllc, posted in Coatings, Corrosion, Forensic Chemistry, Handheld XRF, Metals, Microscopy, staining

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

Colorimetric Method Development for Determining Bottom Ash Content in Cleaned Out CCR Waste Ponds

by magroupllc, posted in Case Studies, Colorimeter, Microscopy

Color measurement by colorimeter can be a powerful technique for analyzing different materials. A colorimeter measures the color of a material, and generates a numerical representation of the color in one of many available scales. Color can provide information such as whether a material is the color specified, or how different two colors are. As … Continue reading Colorimetric Method Development for Determining Bottom Ash Content in Cleaned Out CCR Waste Ponds
