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 particle with diol ligand is recommended for the analysis of polar and hydrophilic compounds that have limited or no retention on alkyl phases like C8 and C18. Ideal for LCMS use since ion-pairing reagents are not required, and the high organic mobile phases result in efficient solvent evaporation for increased sensitivity. Bioinert coating eliminates adsorption and reduces tailing for compounds that have strong interactions with stainless steel or PEEK surfaces.
