TF2000 Thermal FFF - Polymer Separator

TF2000 Thermal FFF

The most Advanced System for Separation of Natural and Synthetic Polymers and Gel Particles!


Professional Modular System

The new award winning Postnova TF2000 Thermal FFF Series was invented to become the first professional modular Thermal FFF system available. It is completely integrated by the NovaFFF single software platform which runs the entire system from autosampler to detectors. The TF2000 Series incorporates the combined solid know-how and the proven technologies from three decades of leadership in FFF. Due to its unique design the TF2000 Thermal FFF system offers more flexibility, higher robustness and better performance than traditional chromatographic systems. A separation column with stationary phase is not required anymore and consequently the TF2000 technology sets a complete new standard and offers a real alternative to column-based polymer characterization techniques.

Broad Separation Range

The TF2000 system has a wide separation range and is able to separate  small and large molar masses with high resolution. This allows the separation of various polymers, such as starches, polystyrenes, polymethylmetacrylates, synthetic and natural rubbers as well as other elastomers. In contrast to traditional chromatographic separation techniques, such as GPC/SEC, no sample treatment is necessary as the samples can be injected without filtration. This allows the characterization of quite complex polymer samples without any potential alteration and damage. Also, Thermal FFF has no Size Exclusion limit and because of this fact even ultra-high molar mass, branched and cross-linked polymers as well as gels, aggregates and particles can be separated.

Molar Mass and Composition Separation

The TF2000 Series system is based on the Thermal FFF principle, using a temperature gradient as driving force for the separation. Polymers effected by this field show Thermal Diffusion which allows the separation by both the Molar Mass and Chemical Composition. This unique feature allows the separation of different polymer material having the same molar mass. The separation can be further optimized by the use of different eluents and various temperature programs. Therefore, the TF2000 can be ideally used for separation of complex polymer samples in the area of Petrochemical, Adhesives, Rubbers, Polymers and Nanomaterials.

Advanced Thermal FFF Detection

In order to enable the user to fully access this wide application range, the TF2000 Thermal is available with various add-on modules and special FFF detectors, such as Refractive Index (RI), Multi-Angle Light Scattering (MALS) and Dynamic Light Scattering (DLS). All Postnova FFF modules and FFF detectors have been especially designed for FFF and optimized not only for the use with the TF2000 Thermal FFF but also for the other Postnova FFF versions. Additionally, the TF2000 Series has been designed for easy interfacing with existing high-end detection technologies from leading instrument suppliers, so that the user can ideally integrate the Postnova FFF technology into the existing laboratory infrastructure in order to maximize efficiency and investment.
