Preparative TREF and Size Exclusion Characterization of Olefin Oligomers
Preparative TREF combined with high-temperature SEC isolates and quantifies migrating sub-1000 Da polyolefin oligomers to verify food contact safety compliance.
Determining Food Simulants for Polyolefin Migration Testing
Polyolefin migration compliance requires selecting food simulants based on polarity and fat content while accounting for matrix swelling and thermal limits.
Recycled Plastic Food Contact Compliance and Non Intentionally Added Substance Testing Methods
Recycled plastic food contact compliance requires rigorous surrogate challenge testing, non-target NIAS screening, and lot-traced migration verification.
Mass Spectrometry Non Target Screening for Unintended Migrants in Polyolefins
High-resolution mass spectrometry non-target screening identifies toxicologically uncharacterized polyolefin migrants down to sub-10 ppb compliance thresholds.
Recycled Polyolefin Oligomer Identification and Toxicological Screening Basics
Verify recycled polyolefin food contact clearance by combining LC-GC-FID quantification of C10-C50 oligomers with toxicological screening under Cramer Class thresholds.
Recycled Content Claims Priced into a Packaging Tax Line
Recycled content tax claims require lot-specific EN 15343 audit trails and migration reports to withstand customs audits and avoid retroactive landed tax liabilities.
