Hindered amine light stabilizers are an important class of stabilizers that protect synthetic polymers from degradation and thus from changing mechanical and optical properties. The current study presents an HPLC method capable of separating oligomeric hindered amine light stabilizers on a commercially available stationary phase, employing an MS-compatible(More)
The current work describes the development of a CZE method with quadrupole QTOF-MS detection and UV detection for the quantitation of Cyasorb 3529, a common hindered amine light stabilizer (HALS), in polymer materials. Analysis of real polymer samples revealed that the oligomer composition of Cyasorb 3529 changes during processing, a fact hampering the(More)
In the current work, a fast and reliable CE method for characterizing of six hindered amine light stabilizers (HALS), technical products commonly employed as UV-stabilizing agents for various polymeric materials, is presented. These compounds can be monomeric or oligomeric species whereby there is no or only limited information available concerning purity(More)
In recent years, the development of reliable methods for the quantitation of microplastics in different samples, including evaluating the particles' adverse effects in the marine environment, has become a great concern. Because polyolefins are the most prevalent type of polymer in personal-care products containing microplastics, this study presents a novel(More)
