Sepiatec’s new Prep SFC 660 system is a compact yet large-scale unit designed for preparative separations using supercritical fluid chromatography. The unit has been designed for flow rates of up 667 ml/min may be achieved (in the case of a modifier portion of 40 %).
All of the advantages of the SFC technology are combined: Quick separation, a reduced consumption of organic solvents and thus cost, increased safety and an environmentally friendly process. In spite of its remarkable capacity, the Prep SFC 360 system features a compact design with measurements of 150 x 68 x 178 cm (W x D x H), so that integration within a walk-in laboratory hood does not create any problem. Additionally, below the unit, several large fraction vessels or a safety cabinet for solvents may be placed.
A CO2 and a modifier pump are provided, each of them equipped with a 400 ml pump head and approved for a pressure of 400 bar. Up to three different organic organic modifiers can be mixed and used for separations. A third pump with 150 ml head is also provided which can be used for modifier or as an add-on pump.
Beside the column mounting, the injection valve and the UV flow cell are also integrated within the column oven, which is heatable up to 50 °C. Separation columns with inner diameters between 30 and 50 mm and a length of up to 800 mm can be used.
When working in “Single Mode“, up to 8 fractions can be collected (CO2 flow < 180 ml/min); in “Tandem Mode“ 4 fractions are available (CO2 flow > 180 ml/min).
The collection of the fractions is performed in unpressurized state; therefore screening of the vessels for reasons of safety is not necessary. The fraction volume in the Prep SFC 660 system is not limited. Fractions of any size may be collected and simply be tapped for further processing.
