Quantification of Non-Intentionally Added Substances in Food Packaging
Non-intentionally added substance quantification requires high-resolution mass spectrometry screening paired with toxicological threshold evaluation for safe compliance.
Reconciling Converter Additive Masterbatch Dosages with Specific Migration Standards
Reconciling masterbatch dosages with specific migration limits requires calculating active concentration, accounting for thermal loss, and verifying compliance by testing.
Untargeted Screening Chemistry for Post Consumer Polyolefin Recycling
Untargeted screening by GC-MS and LC-HRMS combined with Threshold of Toxicological Concern metrics establishes legal food-contact safety for recycled polyolefins.
Migration Results Reported without Their Simulant or Contact Temperature
A migration number without its simulant and temperature is invalid; exposure medium and thermal regime dictate diffusion and verify regulatory compliance.
Cramer Structural Classification and Migration Limits in Packaging Polymers
Cramer structural classification sets exposure thresholds for unlisted packaging migrants, turning molecular features into defensible specific migration limits.
Dynamic Baseline Integration Routines for Volatile Contaminant Interference Subtraction
Adaptive baseline subtraction routines isolate volatile contaminant peaks from matrix background noise, preventing costly false positive resin lot rejections.
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.
