Polyolefin Non Intentionally Added Substances Identification Basics
Polyolefin non-intentionally added substances require chromatographic screening, Cramer toxicological tiering, and finished article migration verification.
High Resolution Mass Spectrometry Response Factor Bias and Limit Calculations in Polypropylene Decontamination Audits
HRMS decontamination audits require response factor bias corrections to prevent underestimating non-target migrants against food-contact safety thresholds.
Untargeted Mass Spectrometry Screening for Polyolefin Recyclate Compliance
High-resolution mass spectrometry screening paired with surrogate semi-quantification establishes food-contact compliance for post-consumer polyolefins.
Analytical Workflows for Structural Identification of Unknown Migrants in Recycled Polymers
Non-targeted GC-QTOF and LC-Orbitrap screening workflows isolate and structurally identify unknown migrants in recycled plastics to ensure food contact regulatory compliance.
High-Resolution Mass Spectrometry Response Factor Uncertainty Mitigation in Recycled Polyethylene Terephthalate Compliance Verification
Mitigate HRMS response factor uncertainty in rPET compliance by replacing single surrogates with class-matched standards and predictive ionization algorithms.
Analytical Non-Targeted Screening Workflows for Unknown Migrants in Multilayer Packaging
Non-targeted screening workflows require orthogonal GC-MS and LC-HRMS platforms to detect volatile, non-volatile, and adhesive oligomer migrants down to an analytical evaluation threshold derived from toxicological thresholds of concern.
