With the introduction of the SF2000 G Postnova has launched a new type of Gravitational Splitt FFF. The SF2000 G is a the first true completely integrated and modular commercial G-Splitt including online optical particle detection. The machine can be used to separate, fractionate, purify and to characterize microparticles in one step. The attached PN3000 XPT detector allows determination of size and shape of the particle fractions eluting from the channel. The system features a broad separation range from 1 to 300 µm depending on sample nature and has the ability to separate different shaped particle fractions from each other. The SF2000 G is clearly setting a new standard in the area of microparticle fractionation and marks a real break-through in Splitt science. The system is using Postnovas unique G-Splitt FFF channel which can be re-used and cleaned after operation. Special pumps deliver and control all necessary in- and outlet flows and the attached PN3000 XPT detector provides further information about the particle fractions via its powerful software.
