Solid phase extraction (SPE) has become the technique of choice for sample isolation / cleanup and trace enrichment before analysis due to its numerous benefits which include versatility, selectivity, and low solvent usage. The SPE process is based on a selective partition of the compounds of interest between a solid phase, the sorbent, and a liquid phase, the solvent.
Manual SPE procedures can be labor intensive and subject to human error, delays, or sample loss. These challenges have led to the development of automated SPE instruments that were pioneered by Gilson. We offer a variety of solid phase extraction systems using positive pressure and consumables that are adjustable based on your needs and can seamlessly integrate into your lab.
This ASPEC 271 System provides the ultimate versatility by combining flexible, positive pressure solid phase extraction (SPE), precise liquid handling, large bed capacity, and on-line integration with liquid chromatography (LC) systems. With its large cartridge capacity and small footprint, it enables unattended processing of a high number of samples per day for any SPE application, even those requiring multiple cartridge extractions.
This ASPEC® system for positive pressure solid phase extraction (SPE) maximizes throughput by processing up to four samples in parallel. With its small footprint and multiple probes, it is the ideal choice for high-throughput SPE automation on 1, 3, or 6 mL cartridges. Combined with ASPEC SPE Cartridges, it generates reproducible and efficient sample cleanup for clinical, forensic, doping, food, and environmental testing labs.
With a uniform and consistent flow rate, the ASPEC Positive Pressure Manifold improves solid phase extraction (SPE) reproducibility and recovery, even with high viscosity samples. The manifold offers better control among samples and between runs than traditional vacuum manifolds, providing greater confidence in your data. It’s easy to set up and use, so you can start immediately.
Gilson’s Guide to SPE Automation is both a resource and step-by-step troubleshooting handbook. This guide provides a background for the technique and explains the science of SPE. It also offers practical advice for automating workflows via Gilson’s SPE systems and software.
