Polymers and plastics, polymerization
X-ray fluorescence (XRF) spectroscopy has emerged as a powerful technique for both process control and regulatory compliance in the polymers and plastics industry. Quantitative monitoring of the concentration of remaining catalysts by XRF provides accurate control of the polymerization process. Process efficiency is improved. PANalytical’s TOXEL package provides certified standards against which to perform XRF analysis. Manufacturers of plastics and polymers are obliged to meet RoHS/WEEE regulations and ASTM F2617-08 international standards. Legislation defines the maximum allowable concentration for several restricted elements. XRF delivers important advantages compared to other techniques. Sample preparation is straightforward, with no dissolution required. Measurements are non-destructive and results are accurate and reproducible. Thanks to the integral smart monitor program, time-consuming and costly re-standardizations are unnecessary and the resultant data are consistent over long periods, saving time and money. Automated analysis reduces measurement times to a matter of minutes and efficient sample preparation methods support high throughput. Userfriendly software allows routine analysis to be carried out by factory operators.
