The Waters ACQUITY APC (Advanced Polymer Chromatography) System is a high-performance chromatographic platform specifically developed for the characterization of polymers and oligomers. By combining ultra-low system dispersion with dedicated APC columns containing rigid, small-particle packing materials, the system delivers high-resolution size-based separations while significantly reducing analysis time compared with conventional size exclusion chromatography (SEC) or gel permeation chromatography (GPC).

It is designed to support both research and routine analytical laboratories that require accurate molecular weight characterization, efficient method development, and reliable polymer analysis. In addition to polymer chromatography, the platform can also perform conventional liquid chromatography applications, providing greater flexibility for laboratories handling diverse analytical tasks.

Key FeaturesTechnical SpecificationsApplications

Rapid Polymer Characterization
The ACQUITY APC system reduces polymer analysis times by 5 to 20 times compared with traditional SEC/GPC while maintaining excellent chromatographic resolution. Its ultra-low dispersion fluidics and APC column technology improve separation efficiency, particularly for low-molecular-weight oligomers, enabling faster decision-making throughout research, development, and manufacturing.
Flexible Method Development
The system supports automated solvent switching and broad solvent compatibility, making it suitable for a wide variety of polymer separation strategies, including isocratic chromatography, gradient LC, reverse-phase LC, and polymer-specific chromatographic methods. This flexibility helps streamline method development for complex polymer samples.
Broad Detector Compatibility
The ACQUITY APC system is compatible with multiple detection techniques, including refractive index (RI), UV/Vis, photodiode array (PDA), evaporative light scattering (ELS), and advanced detectors such as multi-angle light scattering and viscometry. These detection options enable comprehensive polymer characterization beyond molecular weight distribution alone.
Efficient Column Management
Automated column bank selection, temperature-controlled column management, and rapid calibration workflows improve analytical consistency while simplifying routine operation. Dedicated APC calibration standards further support reproducible molecular weight measurements across different analyses.
