Non-targeted high-resolution mass spectrometry validates recycled polyolefin food contact compliance by identifying unknown migrants below ten ppb safety limits.
Relative response factor adjustments eliminate false-pass compliance screening for non-intentionally added substances in polyolefin recyclate packaging dossiers.
Statistical uncertainty factors for polymer screening convert standard response factor variance into lower tolerance bounds that prevent non-target false negatives.
Deriving ionization efficiency models corrects electrospray response variations in non-targeted NIAS screening, preventing false negatives in recycled resin audits.
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.
Toxicological threshold scoring maps unidentified polymer migrates to Cramer exposure limits, mandating genotoxic screening below 0.00015 mg/kg food.
Expertise is a utility, not a secret. sentiention™ publishes its working knowledge as open reference: intelligence layer covering the materials it sources, the markets it enters, and the reference that serves both.
