How to select filtration devices
Interview on what to consider to ensure you choose the right device for your sample prep application.
Importance of HPLC sample prep
Filtration of both analytical samples and mobile phase solutions using the correct device is a simple and economical way to protect HPLC columns and instruments from particulates. Sample filtration prolongs injector life, prevents capillary blockage, and protects pump valves, which together minimize instrument downtime, maintenance, and associated costs.
Ensuring analytical results
Our HPLC certification ensures that analytical results will not be compromised by extractable filter materials. Our membranes have been tested for compatibility with the common HPLC solvents water, methanol, and acetonitrile, using established HPLC procedures. In addition, we verify low levels of UV-detectable extractables.
Mobile phase filtration
Mobile phase filtration will both degas and remove unwanted particulate. Contamination can cause the plugging of the sinker and column frits, may damage pump valves and block capillaries. We provide simple and effective mobile phase filtration devices and membranes.
