The GERSTEL filtration supplies for use with the MPS Robotic Pro offer an automated, efficient solution for the filtration of samples in chromatography applications. Designed to integrate seamlessly with the GERSTEL MPS, these supplies enhance the accuracy of GC/MS and LC/MS analyses by effectively removing particulates and matrix materials from samples. This filtration process not only improves analysis results but also extends the lifespan of critical system components.

For the filtration to be performed automatically, syringe filters are fitted with a cannula and a transport adapter and are stored on a filter tray. Three different types of filter tray are offered that accommodate a different number of filters.

• A filter tray for 16 filters with membranes of any diameter and with a maximum external diameter of 35 mm.
• A filter tray for 24 filters with membranes of any diameter and with a maximum external diameter of 22.5 mm. This tray is also suitable for DNPH cartridges.
• A filter tray for 40 filters with a membrane diameter of 4 mm.

The GERSTEL MPS Robotic Pro fitted with the filtration option can be used with a variety of filter sizes and types. Filter materials available include cellulose acetate, nylon, PVDF, PTFE, polypropylene, and regenerated cellulose. These come in a 0.2 µm or 0.45 µm porosities, and a range of sizes including 4 mm, 17 mm, 25 mm, and 30 mm to suit all filtration requirements.
