AF2000 MultiFlow FFF - Universal Separator

 

AF2000 HT - High Temperature Flow FFF

 

The Top-Level Flow FFF system for Polyolefin Analysis.

 

Application Range

The AF2000 HT is the special modular Top-Level system of the Postnova AF2000 MultiFlow platform. The system includes special temperature control and runs at conditions from room temperature of 20° up to high temperature of 220°C. This makes the system unique and allows separation of Polyolefins and other macromolecules which require special organic eluents and elevated temperature conditions for analysis. The application focus is in the area of separation and characterization of high molar mass and ultra-high molar mass polyethylene and polypropylene. The AF2000 HT offers the highest working temperature and allows the most harsh conditions and solvents of all Flow FFF system within the AF2000 MultiFlow Platform. The system is ideal for special university and public research groups working in the area of polyolefin and high temperature polymers. Even more suitable is the AF2000 HT also for industrial users from polyolefin manufacturers and chemical companies which seek for an advanced analysis tool for product development and demanding QC applications. The AF2000 HT system is available as stainless version only and can be run with a broad range of organic solvents. The system is using special High Temperature Asymmetric Flow FFF (AF4) channels made from stainless steel and ceramics. As detection principles, Infrared (IR), Refractive Index (RI), Multi-Angle Light Scattering (MALS) and Viscometry (VIS) can be coupled online.

System Hardware

It is Postnova's clear mission to only offer fully optimized and professional FFF hardware, software and support solutions. Therefore the AF2000 HT series is a completely optimized Flow FFF system, which contains all necessary standard modules and components in the package, that are required for a robust, reliable and stable operation. There is no need for assembling and utilizing semi-suited third party HPLC components, which are often just made for other purposes, show less flexibility and are not available in the strict specifications needed for FFF applications. The AF2000 HT system incorporates the complete set of Postnova's proven FFF technologies, such as FocusTech, Ceramic ChannelCartridge and SyringeXFlow. This makes it possible to run the machines even under the harsh high-temperature conditions, where other FFF designs would fail immediately. In the AF2000 HT configuration the system is comprising an Eluent Organizer (PN7205), an Eluent Degasser (PN7520), a stainless steel Eluent Pump (PN1130), a stainless steel Focus Pump (PN1130), a stainless steel Flow FFF Control Module with integrated electronic interface and cross-flow syringe pump (AF2000 Module), a High Temperature FFF Channel Thermostat with integrated High Temparture Auto Injector Holder (PN4050), a special stainless steel ceramic composite Asymmetric Flow FFF channel (AF4) and a Control PC with the NovaFFF software suite for operation of the AF2000 HT system.

Additional System Options

The AF2000 HT Flow FFF is available with different detector options and can be customized for special polyolefin and other high-temperature polyolefin applications.

  • EFS Organic Eluent Filtration System
  • AF4 High Temperature Channel Versions
  • RID Refractive Index Detection System
