Webby FFF. Wyatt Technology’s ASTRA MALS analysis software For a spherical particle, provides calculations for molar mass as well as size and spherical particle concentration, and these may be deter-mined at each eluting FFF fraction in order to obtain imately the same overall volume as the partic detailed size distributions. WebThe aggregate content is a critical quality attribute (CQA) of AAV-based gene therapies. This application note compares analytical separations by size exclusion chromatography (SEC) and field-flow fractionation (FFF), along with detection by UV, fluorescence, and multi-angle light scattering (MALS). The results demonstrate that FFF-MALS is the ...

Web(FFF-MALS) is an ideal technique for resolving and ana-lyzing large AAV aggregates. Using Wyatt Technology’s Eclipse FFF-MALS system, both SE -MALS and FFF-MALS may be performed with a single set of detectors, provid-ing valuable orthogonal characterization of these gene therapy products.

WebWyatt Technology’s FFF system is based on the Eclipse FFF instrument in combination with a pump and autosampler, as shown in Figure 1. Separation takes place in a thin channel which has a porous bottom wall comprising an ultrafiltration membrane supported by a frit (Figure 2). onstriction of the channel outlet causes part of the flow WebWyatt's line of multi-angle static light scattering products couple to size exclusion chromatography (SEC-MALS), field-flow fractionation (FFF-MALS) and stop-flow composition-gradient systems (CG-MALS). Our dynamic light scattering (DLS) products operate in traditional cuvette as well as on-line and automated, high-throughput modes. WebAnother powerful separation technique often used in conjunction with MALS is Field-Flow Fractionation (FFF) which performs separations over a very wide dynamic range. FFF works without a packed column, by means of a channel. ... Wyatt Technology is the recognized leader in light scattering instrumentation and software for determining the ... cd drive close
