Low Dead Volume Precolumn Filter with 0.5 μm Stainless Steel Frit can be used to protect the TSKgel columns. When working with columns that contain smaller than 5 μm particles, Tosoh Bioscience suggests the installation of a pre-column filter in front of the (guard) column to avoid clogging the top frit. In addition, when suspecting debris from the breakdown of pump seals, it is beneficial to use a pre-injector membrane filter to prevent any particulates from reaching the injector and/or (guard) column.
