Candidate List Duty Triggers in Component Level Imports
Candidate List duties trigger when any discrete component article exceeds 0.1 percent SVHC by weight, regardless of aggregate assembly mass.
Analytical Screen Isolation Methods for Polymeric Matrix Additives in Minor Assemblies
Screening polymeric minor assembly additives requires precise cryo-milling, solvent extraction, and mass spectrometry to confirm regulatory compliance limits.
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.
Quantification Uncertainty of Semi Volatile Non Intentionally Added Photoinitiators in Recycled Polyolefin Streams
Quantifying semi-volatile photoinitiators in recycled polyolefins requires matrix-matched standard addition to counter 40% measurement uncertainty.
Quantification Limits of Non-Aqueous Volatiles in Post-Consumer Polyester Desorption Titrations
Thermal desorption titration quantifies non-aqueous volatiles in rPET down to 2.5 ppm when cryogenic milling eliminates diffusion limits and baseline drift is corrected.
Non Intentionally Added Substance Screening Methods in Recycled Polyolefin Resins
Recycled polyolefin NIAS compliance requires high-resolution mass spectrometry screening paired with Cramer structural toxicological limits down to 0.15 ppb.
