Shim-pack Scepter PFPP-120 [Metal Free], 1.9um, 2.1 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 organosilane hybrid particle with a pentafluorophenyl ligand provides alternate selectivity to a C8 or C18, and is recommended for the analysis of aromatic and positively charged (especially N-containing) compounds. The PFPP phase can be used in reversed-phase mode with 100% aqueous conditions, or in HILIC mode for increased LCMS sensitivity. PLS hardware eliminates adsorption and reduces tailing for compounds that tend to form chelates with metal surfaces, especially those containing phosphate groups. USP L43, pore size: 120A, pH range: 1-8, max pressure: 100 MPa/1000 bar/15,500 psi, 15% carbon load, non-endcapped. Phase is simlar to Acquity BEH PFP; PLS hardware is unique.
