Thermal Field-Flow Fractionation: Ultra-Broad Polymer Separation TF2000-MALS - Molar Mass by Thermal FFF & Multi-Angle Light Scattering
Product News Nov 12, 2009
The TF2000-MALS series is technically comparable to a GPC-MALS system, but without having the disadvantages of common SEC/GPC technology. The column is replaced by a special separation channel without any stationary phase inside. Separation and retention takes place under the influence of a thermal separation field gradient. Polymers and particles, such as starches, rubbers and latex particles, can be easily separated from 10E4 to 10E9 Da and from 1 nm to 10 µm. Contrary to GPC, the Thermal Field-Flow Fractionation does not have a size exclusion limit, which confines the separation of high molecular mass samples.
Ultra-high resolution and extremely broad separation range
No shear forces and gentle separation conditions for polymers
Lower flow rates and reduced solvent consumption compared to GPC
Re-usable channel without consumables; no need to purchase columns
The Postnova TF2000-MALS system comprises of a Thermal Field-Flow Fractionation separation unit plus the seamlessly integrated Multi-Angle Light Scattering and Refractive Index detection units. The NovaFFF Software platform controls the complete FFF-MALS-RI system, acquires the data and allows the direct calculation of the corresponding molar mass and size. Other detectors, such as UV, Fluorescence and ELSD can be connected as well.
By presenting the new TF2000-MALS Series, Postnova has reached the next level of perfection in Thermal FFF-MALS technology. The TF2000-MALS Series provides an invaluable tool to any researcher who is in the need of characterizing complex, broad distributed, sticky, high molar mass and gel-type materials. The technology offers the important advantage of a huge separation range on the one hand and a superb separation performance on the other hand. Polymers and particles can be separated and analyzed with unprecedented accuracy and with higher resolution than in chromatography, avoiding all the drawbacks associated with packed columns. All together this makes the TF2000 Series the new standard technology for polymer and particle separation.
