Features of Viscotek HT-GPC
- Dual piston pump optimized for HT-GPC, with extremely low pulsation and stable eluent flow to improve detector performance. * Temperature controlled environment for up to 7 columns, injector and up to three detectors. Operates up to 160°C * Automated sample preparation using the Vortex autoprep/autosampler. Operates up to 170°C with no user intervention, making the system safe, accurate and productive. * Automated sample filtration reduces the number of preparation steps - only the sample injected on the column is filtered, which avoids bulk filtration and improves lab safety (no manual handling of hot solvents). * High sensitivity viscometer, with unrivalled baseline stability and the widest application flexibility. * Digital Inert Transducer (DIT) technology for faster, more sensitive response. * Unique 7° Low Angle (LALS) detector measures the absolute MW directly without data fitting, extrapolation or correction. * 90° Right Angle (RALS) detector provides the best signal to noise ratio and the highest sensitivity for small molecules. * Accurate measurement of the polymer concentration using a refractive index detector.
