Introduction

In recent years, new developments in the area of Size Exclusion Chromatography (SEC) have resulted in the introduction of Ultra High-Performance Liquid Chromatography (UHPLC or UPLC^®) for polymer applications. Waters ACQUITY Advanced Polymer Chromatography (APC™) is a breakthrough technology that is able to provide SEC analyses of polymeric materials with higher-resolution and higher-speed than conventional SEC.

The new APC technology involves the use of high efficiency separation columns and a low dispersion flow path, resulting in:

• High resolution analysis
• Reduced time
• Reduced solvent consumption
• Reduced sample concentration
• Quick mobile phase changeover

However, the APC system is limited to conventional calibration, meaning it can only generate relative molecular weight information. In order to obtain comprehensive knowledge of the polymers under analysis, it is necessary to combine the high-resolution APC system with additional advanced detectors.
