EDXRF Analysis of Polymer Film

Shimadzu’s original “Background FP Method” (hereafter referred to as the “BG-FP method”) iseffective for determining the thickness of polymer films such as polyethylene and polyester. Thismethod incorporates X-ray scattering theory calculation into the FP method. By applying theprinciple that the intensity of the Compton scattering lines made by a polymer film is proportional toits thickness, the thickness of the film can be determined in air at the same time as content of itsconstituent elements. Shown below are tow examples of this.
