Frits are surrounded with a ring of PEEK to reduce the actual porous surface to the ID of an HPLC column. The compressed PEEK ring forms a seal between the bottom of the fitting and the column end, preventing the mobile phase and the sample from entering the previously accessible, poorly swept areas.
PEEK-encased frits with 0.115" or 1/4" OD rings are intended for HPLC columns with IDs of 2.0, 3.2, 3.9, and 4.6 mm.
NOTES
Stated frit porosities are only nominal and do not reflect the maximum pore size of a frit.
