This application note demonstrates the successful use of the fully automated the EXTREVA ASE system for the extraction of plastic additives in packaging. Additives were confidently identified by liquid chromatography and Orbitrap-based high-resolution accurate mass (HRAM) mass spectral analysis. The EXTREVA ASE technique delivers comparable or more efficient extractions than the traditional 10 h static liquid extraction. The EXTREVA ASE system combines extraction and evaporation in one unit, which significantly reduces manual labor cost and increases sample throughput.
This application demonstrates reliable verification and quantification of the presence of extraneous compounds in a sample, such as impurities, degradation products or extractables and leachables.
Accelerated Solvent Extraction (ASE) is a powerful technique that can be used to reliably extract additives from polymer materials. ASE uses organic solvents at temperatures above their atmospheric pressure boiling points to deliver extractions equivalent to traditional extraction techniques, but with faster extraction times, reduced solvent use, and automation of the extraction process. ASE is recognized as an official extraction method in U.S. EPA Method 3545.
