Product Details
Features
- Accurate molecular weights – light scattering detection does not require column calibration and when combined with PLgel columns delivers perfect results about the true polymer molecular weight, size, shape, and long chain branching
- Accurate size and structure – viscometry can be used to measure Rg (sample radius) and sample structure over a wide molecular weight range extending from millions to tens of Daltons, and connects with light scattering to give the ultimate detector combination
- Minimal dispersion – a low-volume light scattering detector flow cell of just 10 μL ensures correct values for polydispersity
- Efficient, reproducible answers -– each detector is independently temperature controlled from 30 to 60 °C to ensure high baseline stability and minimal baseline drift
- Fully upgradable – to expand the system’s capabilities, you can upgrade at any time from a single, advanced detector to full triple detection
- Simple instrument operation – in a single software solution you get complete instrument control, data collection, and data analysis from conventional GPC through to triple calculations
- Low molecular weight sample analysis – the viscometer can measure molecular weights down to as low as 100’s thanks to the latest advances in silica and pressure transducer technology
- Versatile – any combination of detectors is possible and a touch-sensitive keypad enables easy operation or fast visual inspection of status summary; full control is through the Agilent GPC/SEC software
- Triple detection delivers the ultimate in polymer analysis – absolute molecular weights are determined by light scattering detection and molecular size and solution behavior comes from the light scattering and viscometry detectors

Additional Information
Light scattering and viscometry detectors
Because GPC separates polymers according to size rather than molecular weight, the results obtained for molecular weight are simply related to a column calibration. Standards for calibrating a column are often very different from the polymer of interest so the results obtained are very different from the actual values. This limitation can be overcome by using light scattering and viscometry.
The 1260 Infinity II Multi-Detector GPC/SEC System includes both light scattering and visometry detectors and represents a comprehensive solution that enables complex multidetector GPC experiments to be performed routinely. The ultralow dispersion of the system delivers ultimate performance for accurate and reproducible molecular weights. Vital for any modern laboratory, a dependable, reliable system is essential to ensure high sample throughput and efficiency. The system is ready to run as soon as you are
- The flow cells of both detectors can be heated to 60 °C, ensuring stable baselines and excellent signal-to noise performance.
- The flow cells also have the lowest volume commercially available, reducing dead volume, minimizing band broadening and therefore increasing precision, accuracy, and reproducibility for ultimate confidence in results.
- The advanced optical design of the light scattering detector drastically reduces baseline spiking that is commonly seen at low angles.
- Light scattering gives accurate molecular weight, size, and structural information. No column calibration is required.
- The viscometer measures the intrinsic viscosity of the polymer and gives information regarding molecular size, polymer branching, and density as well as details of any aggregation.
- Combining the two detectors creates the ultimate configuration for comprehensive polymer characterization. User-friendly multidetector software provides a wide range of options for both calculations and reporting.
