33 1 3048 7200ACQUITY APC AQ columns are designed to provide highly efficient size-based separations for water soluble polymer characterization. The sorbent uses patented Ethylene Bridge Hybrid (BEH) technology to provide a mechanical strong packed bed that resists shinking and swelling for easy mobile phase solvent switching. The expected molecular weight range for this column is approximatley 1, 000 - 30, 000 g/mole.

Achieving superior performance and reliability with high resolution polymer characterization can be a challenge. ACQUITY Advanced Polymer Chromatography (APC) Columns are designed for polymer scientists like you, with novel capabilities for chromatographic efficiency, speed and resolution that cannot be matched by conventional GPC methods. With these columns, you can quantify and characterize polymer samples with confidence and accuracy while maximizing productivity.
The Ethylene Bridged Hybrid (BEH) particles used in ACQUITY APC Columns enable rapid solvent switching and the ability to use multiple conditions for the same bank of columns. Conventional polymeric stationary phases are dedicated to a single set of analytical conditions and solvent because the chromatographic bed is vulnerable to shrinking and swelling. By eliminating this undesirable behavior, ACQUITY APC Columns allow for maximum robustness and method development flexibility.

Use multiple conditions for the same column bank with rapid solvent switching using the rigid hybrid particles in ACQUITY APC Chromatography Columns. Conventional polymeric phases are often dedicated to single analysis conditions because the chromatographic bed is vulnerable to shrinking and swelling that can be potentially harmful to the column. By eliminating this constraint, ACQUITY APC Chromatography Columns provide more freedom for method development and deliver advanced polymer characterization for a diverse range of samples.
With long conventional Gel Permeation Chromatography (GPC) run times of up to one hour or more, analyses of standards and samples can be quite time-consuming. In addition to long GPC run times, the large extra-column volume of conventional GPC systems can result in peak bandspreading, reducing the resolution and thus accuracy of the calibration points. Combined with the lower dispersion ACQUITY APC System, small particle ACQUITY APC Columns deliver less bandspreading and narrower, sharper peaks compared to the conventional GPC system. Additionally, robust sub-3-µm APC Column Technology supports higher flow rate and backpressures, thereby improving resolution.

Reproducible column performance is one of the most critical factors for achieving long-term method reliability during polymer characterization. Each step of our column manufacturing process is monitored and tightly controlled to maintain unmatched product reproducibility. Every test, from raw material characterization to final batch analysis, is designed to ensure that ACQUITY APC Columns perform the same from column-to-column, batch-to-batch, and year-to-year.
