“…The elution volume of the main peak of Phosphite TNPP corresponds to larger molecules than that of the Polygard peak. It is often difficult to determine the composition of the individual compounds in such samples [15]. It can be said, nevertheless, that GPC analysis will demonstrate the composition of the organophosphorous stabilizers better than chemical analysis.…”

“…There are specific advantages in the analysis of the polymer extracts by gel chromatography. This method was used successfully in analyzing phenolic and aminic antioxidants [11][12][13][14][15] and plasticizers [ 16,171 . This paper reports on the results obtained by GPC analyses of important stabilizers and plasticizers used in the preparation of PE and PVC foils.…”

Gel permeation chromatography (GPC) method, either alone or in combination with thin‐layer chromatography (TLC) or PC, has been used for determining the number of mononuclear and binuclear phenolic antioxidants used for the stabilization of polyethylene, and of some organophosphites and organotin compounds suitable for the stabilization of poly(vinyl chloride) (PVC). A differential flow refractometer and a UV detector were used for the detection of the compounds by GPC. Qualitative determination of the components of more complex mixtures is facilitated by the use of a curve resolver. Particular attention has been devoted to the types of stabilizer approved by the food codex. The data on PVC stabilizers have been complemented by the Ve values of the plasticizers, and their interference with the stabilizing components has been investigated. The control analyses have been carried out on mixtures of stabilizers and polymer extracts.

“…It has been also reported that additives used by manufacturers frequently contain amounts of other compounds apart from the main active component. 9 There have been a number of reports of finding contamination of these compounds in food and pharmaceutical products. Migration from packaging materials to drug contents generally does not involve major macromolecular components, such as the polymer itself (which is intrinsically odorless, tasteless, and nontoxic), but is concerned with minor constituents which can and do affect the quality of the contained product by sensory or toxicological hazards.…”
