GL Sciences VPS2800 GC Fraction Collector
The GL Sciences VPS2800 GC Fraction Collector is designed for preparative gas chromatography applications requiring high recovery and precise fractionation from GC capillary columns. It enables selective collection of complete peaks, partial peaks, or defined groups of peaks based on chromatographic or time-window criteria. A highly inert, fully deactivated internal flow path combined with elevated transfer line and manifold temperatures ensures efficient recovery, including for high-boiling compounds, while maintaining sample integrity.
The system incorporates an electrically driven Stirling cooling mechanism capable of achieving trapping temperatures down to −60°C without the use of liquid nitrogen. This closed-circuit electronic cooling approach provides stable, low-cost and environmentally safe operation. Up to six collection traps and one waste channel are supported, with contamination prevention achieved through dedicated sealing gas for inactive traps. Collected fractions can be directly transferred for downstream analysis such as NMR, UV/Vis, or GC-MS, or used for further purification or reanalysis.

Features
- High-Purity GC Fraction Collection – Designed for preparative GC using capillary columns, enabling collection of partial peaks, individual peaks, or grouped peaks with high recovery
- Stirling Cooling Technology – Achieves trapping temperatures down to −60°C without liquid nitrogen, providing stable, low-cost and environmentally safer cooling
- Highly Inert, Deactivated Flow Path – Minimises adsorption and carry-over, ensuring precise and reproducible fractionation
- No Cold-Spot Design – Heated transfer line and manifold (up to 380°C) prevent condensation and improve recovery of high-boiling components
- Multiple Collection Traps – Supports six collection traps plus one waste channel, with separate sealing gas to prevent cross-contamination of inactive traps
- Automatic or Manual Collection Modes – Fractions can be collected automatically based on chromatographic peaks or time windows, or manually as required
- Easy-to-Use Software Control – Software interface allows peak selection directly from the chromatogram and provides full temperature monitoring and control
- Universal GC Compatibility – Can be installed on most gas chromatography systems without modification
- Efficient Thermal Management – Super-insulated oven with active cooling fan and specially shaped preparative tubes to maximise trapping efficiency
- Low Operating Costs – Electronic cooling eliminates liquid nitrogen consumption, reducing running costs and operational complexity
