Expertise/Polymers and plastics, additives and fillers
Additives and fillers are routinely added to plastics during manufacture to enhance or suppress specific properties. Some can be hazardous to humans and wildlife. Accurate elemental analysis ensures tight control of these expensive chemicals during polymer production. X-ray fluorescence (XRF) spectroscopy has become an established analytical method for quantifying the concentrations of additives and fillers. Being a nondestructive technique, XRF delivers important advantages compared to other methods. Sample preparation is straightforward, with no dissolution required. Measurement 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. User-friendly software allows routine analysis to be carried out by factory operators.
