Column, LC, Shim-pack GISS-HP Guard Column C18, 1.9um, 2.1x10 with Cartridge (2pcs) and Holder Ideal for Rapid Analysis. Shim-pack GISS C18 maintains the same ultra-high inertness and wider pH range as the Shim-pack GIST C18, while providing rapid separations with symmetrical peaks. The optimization of surface area, pore size and chemical bonding delivers superior peak shapes. It is ideal for LC/MS/MS analysis and enables MS-compatible buffers to be used due to extremely inert silica gel. Bonded Phase: Octadecyl Groups, Particle Size: 1.9 ?m, 3 ?m, 5 ?m, Pore Size: 20 nm, Surface Area: 200 m2/g, Carbon Loading: 9 %, End-capping Yes, pH Range: 1 to 10, USP Code: L1.
Column, LC, Shim-pack GIS Guard Column RP-Shield, 5um, 1.5x10 with Cartridge (2pcs) and Holder Embedded with a Polar Functional Group. Shim-pack GIS RP-Shield contains a polar functional group embedded between silica surface and an octadecyl group, making it stable in 100% aqueous mobile phases without phase collapse. The embedded polar functional group is also extremely base deactivated, which enables the column to provide superior peak shape for acids. Shim-pack GIS RP-Shield provides unique selectivity as hydrogen bonding interactions, making it suitable for separations that cannot be achieved by other modes, such as hydrophobic interactions or pi-pi interactions. Bonded Phase Octadecyl Groups, Particle Size 5 ?m, Pore Size 10 nm, Surface Area 450 m2/g, Carbon Loading 9 %, End-capping No, pH Range 2 - 7.5, USP Code L1.
