The Scepter Claris column has a bioinert surface treatment on the column body and frit for a completely metal-free flowpath. It is ideal for the analysis of compounds that adsorb to either stainless steel or PEEK. The organosilane hybrid particle with C8 ligand is less retentive than a C18 and is suitable for a wide variety of applications and mobile phase conditions up to pH 12. Bioinert coating eliminates adsorption and reduces tailing for compounds that have strong interactions with stainless steel or PEEK surfaces. USP L7, pore size: 120A, pH range: 1-12, max pressure: 100 MPa/1000 bar/14,500 psi, carbon load: 17%, fully endcapped.
