Shim-pack GIST C18, 5um, 3.0 x 50mm LC Column

Shim-pack GIST columns consist of fully porous silica with superior inertness for improved analytical performance and long lifetime. The C18 ligand is a general-purpose phase for nonpolar compounds, and can also be used to analyze strong ionic compounds that have limited retention on other phases. The GIST C18 produces symmetrical peaks with high reproducibility and has an extended pH range (1-10) compared to many other C18 columns, allowing use under alkaline conditions This dimension is recommended as the delay column for PFAS analysis by LCMS. USP L1, 100A pore size, 350 m2/g surface area, 14% carbon load, pH range 1-10, fully endcapped. Maximum pressure 45 MPa/450 bar/6,500 psi.
