ExcelPlas Labs Develop ATR Method For Sampling Purity and Quality of Geomembranes
Oxidation, degradation, contamination, incorrect material could cause brittleness, cracks, and weakness of your geomembrane.  Excelplas has developed a sample testing plan for these symptoms by analysing for these issues using single-bounce ATR.  To identify the problem, we compare the sample to the reference material, identify unexpected components, and ensuring the material is fit for purpose.  The method uses a FT-IR Spectrometer outfitted with an Attenuated Total Reflectance (ATR) sampling accessory with a single bounce diamond crystal, which is ideal for the analysis of black polyethylene geomembranes.  Email: [email protected]
