ACQUITY APC™ Columns deliver advanced sorbent technology for separating complex synthetic polymer and macromolecular species. They deliver superior performance and reliability for high resolution polymer characterization compared to conventional GPC columns. ACQUITY APC Columns improve advanced polymer chromatography by: ◾Improving Bed Stability. ACQUITY APC Columns eliminate the shrinking and swelling that often occurs with polymeric stationary phases upon solvent switching. ◾Maximizing Efficiency. The optimized pore volumes and particle sizes provide unmatched separation speed, resolution and chromatographic efficiency. ◾Providing Industry Leading Reproducibility. Each step of our column manufacturing process is tightly controlled to deliver exceptional product reliability.
Advanced Polymer Chromatography
Representing an industry first, APC Calibration Standards were specifically designed to match the molecular weight range of the ACQUITY APC XT Columns. They eliminate the need to manually prepare custom standard calibration mixes as ACQUITY APC Calibration Standards provide the right number of data points for the targeted MW range. In addition, calibration time on the ACQUITY APC system is reduced by a factor of 3-5x, enabling higher confidence in the accuracy of your results by performing more frequent calibrations. Due to LC system, sample preparation and laboratory environment variances, routine calibration is critical to achieving high accuracy in MW determination.
The ACQUITY APC Standards are available in both polystyrene and polymethylmethacrylate configured into Low, Middle and High Molecular Weight Calibration Kits. They are also available in convenient Method Development Kits to include the full separation range of all three kits combined.
The ACQUITY APC Columns Selector will assist you in choosing the set of columns and calibration standards for your analysis.
Stationary Phase Characteristics
The ACQUITY APC Column brand provides the necessary tools used to separate the most complex polymer samples. The following table will help in choosing the correct column bank.
The synthetically engineered Ethylene Bridged Hybrid (BEH) particle delivers outstanding chromatographic column performance and long lifetime under harsh operating conditions. The particle is prepared from two high purity monomers: tetraethoxysilane (TEOS) and bis(triethoxysilyl)ethane(BTEE), resulting in a highly stable and mechanically-strong particle.
Rapid Solvent Switching
The rigid hybrid particles used in ACQUITY APC Chromatography Columns provide unprecedented capacity for rapid solvent switching, making it possible to use multiple conditions for the same column bank. 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.
Superior Separation Performance
ACQUITY APC Columns are designed for polymer scientists who require high resolution polymer characterization and column efficiency. ACQUITY APC Columns introduce new capabilities for chromatographic efficiency, speed and resolution that cannot be matched by conventional methods. They provide the ability to quantify and characterize polymers samples with confidence and accuracy while maximizing productivity.
Reproducible Column Performance
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.
