Polymer Grade Monomer Analyzers
The production of polymers requires high-purity 99.9+% (polymer-grade) monomers. Ethylene and propylene are commonly used as feed stocks for production of polyethylene, polypropylene, and other chemicals. These polymer-grade monomers usually contain low levels of other hydrocarbons, sulfur compounds, and other impurities that can reduce catalyst lifetime, affect product quality, and impact process yields.
Agilent provides a family of factory tested - ready to use GC analyzers for the analysis of impurities in ethylene and propylene samples using FPD, FID, PDHID as well as MSD detectors and combinations thereof. Whether you select from one of our turnkey configurations or require a custom analyzer, Agilent will consult with you to define the right solution.
- Custom analyzers based on industry leading 7890 GC and MSD provide analysis for maximum number of analytes including Arsine and Phosphine.
- PDHID for quantitation of low levels of Hydrogen, Oxygen, and Nitrogen.
- Methanizer for detection of low levels of CO and CO2 by FID.
- Optional Dynamic Blending System assists with calibration.
