Expertise/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.

Non-ambient components/Applications

The Chimera chamber is designed for in situ powder X-ray diffraction studies of both organic and inorganic compounds at low and medium-high temperatures. Typical applications of the Chimera cryostat are studies of dynamic structural changes or phase transformations, where it is extremely important to move very slowly and accurately through the specific temperature range. In addition to powder XRD, the reflection geometry enables basic measurements of thin films and solids (phase identification, residual stress and basic reflectometry).

Non-ambient components/Applications

Cryostream Plus compact is designed specifically for Empyrean and X’Pert³ Powder (X’Pert PRO MPD) diffractometers and is optimized for in situ high-resolution powder X-ray diffraction studies of both organic and inorganic compounds. The capillary transmission geometry allows to achieve superb low-angle performance and to minimize preferred orientation effects. Furthermore, the transmission geometry enables total X-ray scattering measurements for pair distribution function analysis (PDF) and basic SAXS measurements.
