Postnova SF2000 GS (Gravitational SPLITT) series

Preparative particle fractionation

SPLITT fractionation utilizes the well-controlled hydrodynamics found in thin cells and the simplicity and flexibility of an externally applied field. The high stability of flow leads to high resolution separations and reproducible results. Since a known field is applied, the separation is predictable and can be fine-tuned for individual samples. The field, typically gravitational in nature, is oriented in a direction perpendicular to the laminar flow of the carrier fluid through the cell. When the field is provided by the Earth's gravity, the overall cell design is a simple flow channel, whereas, when a centrifugal field is used, the channel design is more complex.
