GC Preparative System VPS2800

The VPS2800 Preparative Gas Chromatograph System by GL Sciences can collect target compounds which were separated by Gas Chromatography. A highly inert and unique internal flow path is introduced with the VPS2800.

With a unique flow path there is no absorption or contamination. Components coming from the column, passes through the manifold and are recovered in one of the preparative tubes by switching the back pressure gas. In order to prevent contamination, the VPS2800 uses a separate gas for sealing the entrance of the preparative tube that is not in use. The unique deactivation of the sample lines reduces the absorption, resulting in very precise fractions of the chromatogram.

The VPS2800 is equipped with a next-generation electronic cooling function. The Stirling cooler is a completely new cooling mechanism, it uses the intake and exhaust heat during compression and expansion of the refrigerant gas (Helium) in a closed circuit. The Stirling cooler is electrical driven and no liquid nitrogen is needed for cooling. This cooling function result in very low trapping temperatures without the need of cryogenics like LN₂ or CO₂.
