Compression molding of polymer samples for XRF analysis

High-quality results from a simple, robust and versatile benchtop system

High-quality, reproducible and reliable XRF analysis of polymer samples can be achieved using a benchtop pressing system for the sample preparation. This brings the full power of ED- or WDXRF analysis of polymer samples to every lab, assuring constant product consistency from the raw material analysis to the quality control of the final goods.

The most common presentation form for raw polymer materials (virgin or recycled) is as granulates with chips and powders also being of widespread use. The accurate and reliable analysis of such materials by X-ray fluorescence spectrometry requires them to be compression-molded (hot-pressed) into flat, homogeneous disks. Only in that form can XRF spectrometers deliver their full capabilities with maximum reproducibility and accuracy.
