Polyolefin Low Molecular Weight Extraction and Migration Testing
Polyolefin migration compliance requires batch-specific testing for low molecular weight hydrocarbons using accredited simulants, exact temperatures, and GC-MS.
Standardizing Chromatographic Isolation Procedures for Dual Use Migrants in High Fat Packed Matrices
Chromatographic isolation of dual-use migrants from fat matrices requires GPC or SPE lipid cleanup to prevent mass spectrometry ion suppression and false negatives.
A Declaration of Conformity Covering Only the Base Polymer
Base polymer declarations certify monomer purity at the reactor gate but omit all converter additives, breakdown products, and finished article migration limits.
