Polymer Stabilizer Analysis
Chromatography analysis is used to determine the identities and quantities of stabilizers in plastics.

Antioxidants are used to protect polymers from oxidative degradation during processing and while in use. Antioxidants can be both primary antioxidants and secondary antioxidants.
Primary Antioxidants
Secondary Antioxidants
Alkyl Radical Scavengers
Light stabilizers are used to protect polymers from degradation by UV light. This class includes UV Absorbers and HALS.
UV Absorbers
HALS (Hindered Amine Light Stabilizers)
HALS are measured using size exclusion chromatography with photodiode array detection (SEC-PDA).
Phenolic antioxidants are measured using a reverse phase high performance liquid chromatography (HPLC) method. This method is based on ASTM D6042, “Standard Test Method for Determination of Phenolic Antioxidants and Erucamide Slip Additives in Polypropylene Homopolymer Formulations using Liquid Chromatography (LC).”
Generally, at least 100 mg is required per method. Methods cannot identify materials other than those included in the standards mixture. We ecourage you to talk with our experts today and request a quote.
We have decades of experience analyzing materials and finished products for polymer stablizers. Some examples of our experience include:
