For HPLC columns or in-line filters, these titanium frits are recommended for protein analysis. The frit is critical for contributing metal ions to the mobile phase and interacting with protein samples. Titanium frits are biocompatible and have higher corrosion resistance.
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.
TECH TIP
We recommend 2 μm frits for columns with 5 μm or larger particles, and 0.5 μm frits for smaller particles.
NOTES
Stated frit porosities are only nominal and do not reflect the maximum pore size.
OPTIONS
Other dimensions and porosities are available on request. The minimum order quantity depends on the dimensions. Please contact your local distributor or VICI Jour directly.
