Background

In the production of polymers such as polypropylene (PP), polyethylene (PE) and polyethylene terephthalate (PET, PETE) various additives and stabilizers are added, as well as Si (as SiO₂) as an anti-block. Trace levels of catalyst residues may also be present. To ensure proper quality control during the production process test samples are made and the trace elements are measured. To meet this industry need Applied Rigaku Technologies offers a full line of benchtop EDXRF analyzers. With simple, intuitive software interface and powerful, innovative design, Rigaku NEX QC+ makes an excellent tool for quality control check at several places along the polymer production process.
