Shim-pack Scepter C4-300 [Metal Free], 3um, 4.6 x 50mm LC Column

The bioinert Scepter column has a PEEK-lined stainless steel body with a high pressure polymer frit for a completely metal-free flowpath. The C4-300 phase is recommended for mid- to large-sized molecules (above 5000 MW) to ensure retention and avoid size exclusion effects. It is ideal for LC and LCMS analysis of peptides, proteins, intact monoclonal antibodies and their subunits up to 150 kDa. PLS hardware eliminates adsorption and reduces tailing for compounds that tend to form chelates with metal surfaces, especially those containing phosphate groups. USP L26, pore size: 300A, pH range: 1-10, max pressure: 45 MPa/4500 bar/6,500 psi, fully endcapped. Phase is similar to XBridge Protein BEH C4, PLS hardware is unique.
