Secondary Packaging Polymer Recycling Contamination Baseline Assessment Methods
Recycled secondary polymer baseline assessment requires volatile headspace screening and mineral oil quantification to prevent migration across primary packaging.
Resolving Saturated Polyolefin Oligomer Humps from Mineral Hydrocarbons in High-Density Polyethylene Declarations of Conformity
Polyolefin oligomer humps in HDPE mimic mineral oil on LC-GC-FID; compliance requires GCxGC-TOFMS spectral deconvolution and specific migration on Tenax.
Chromatographic Deconvolution of Polyolefin Oligomeric Saturated Hydrocarbons and Petroleum Mineral Oil Fractions
Chromatographic deconvolution requires silver nitrate epoxidation or GCxGC-TOF-MS fragment ratios to isolate polyolefin oligomers from mineral oil limits.
Deriving Cramer Class Thresholds for Unresolved Polyolefin Hydrocarbon Humps
Deriving polyolefin hydrocarbon hump compliance requires LC-GC-FID fraction isolation and Cramer Class derivation to set verifiable limits against migration test data.
