ECLIPSE

Field-Flow Fractionation for the most versatile separations of complex fluids.

Flatten the learning curve and increase your productivity. Wyatt offers a suite of unmatched software tools for designing, performing and analyzing FFF-MALS experiments.

For maximum convenience, use the VISION CSH® software hub to launch Wyatt's native FFF method development, instrument control and data analysis packages: SCOUT DPS®, VOYAGER CDS® and ASTRA®.

Eclipse FFF systems can also be controlled from plug-ins residing within industry-standard HPLC software. If you are familiar with OpenLab®, ChemStation®, Chromeleon® or LabSolutions®, easily set up enhanced separations using the Eclipse plug-in.

  • One hub to launch them all

    VISION Chromatography Software Hub serves as FFF Central Station on your lab PC. Open VISION to launch any and all of the primary Wyatt software packages for FFF-MALS:

    SCOUT DPS
    Combines simplified, rationalized FFF method development with FFF data analysis to determine distributions of hydrodynamic radii based on first-principles physics.
    VOYAGER CDS
    Complete, integrated solution for FFF experimental runs. Instrument control and data acquisition for Eclipse and Agilent HPLC components.
    ASTRA
    Wyatt's flagship software for characterization of macromolecules and nanoparticles by SEC/FFF-MALS. Acquires, analyzes and reports measurements from multi-angle light scattering, dynamic light scattering, UV/Vis, dRI and differential viscometry detectors. Determines molar mass, size, concentration, intrinsic viscosity, conformation, shape, particle concentration (number density) and more.

  • Rationalized method development

    The flexibility of FFF allows users to achieve excellent separations for most applications, but in some cases finding the optimal method for the separation run can require tedious trial-and-error.

    SCOUT DPS is an indispensable tool for FFF method development which utilizes in-silico, "virtual" experiments to eliminate most of the time and effort required for FFF method development.

    Typical method optimization in SCOUT combines the results of one or two real FFF runs with an unlimited number of virtual FFF runs. A proprietary simulation algorithm quickly calculates the effect of changing parameters such as:

    • Channel flow rate
    • Cross-flow rate gradients
    • Spacer height
    • Membrane porosity

    From virtual to physical

    SCOUT makes use of first-principles FFF physics to simulate the separation process. The results are shown immediately, including the effect of band broadening and dilution of the sample at the channel outlet.

    The example to the right shows the process for optimizing a nanoparticle separation.

    • The blue experiment is the result of a default method for separating a sample containing three nanoparticle sizes. The dashed blue line shows the cross-flow gradient used, and the solid blue line is the measured concentration signal.
    • The red experiment is the result of a series of simulations tested to improve the resolution. With a modified cross-flow gradient, the peaks are expected to exhibit baseline resolution.

    The final measurement shows that the optimized method performed well, with enhanced separation between the three peaks.

    Added value: Rh

    An additional benefit of SCOUT is the analysis of fractograms to determine size distributions according to basic FFF physical theory.

    This graph shows the size distributions determined for the nanoparticles in terms of hydrodynamic radius.
