Shimadzu, 227-30271-02, Shim-pack GIS (G) CN, 3um, 1.5 x 10mm LC Guard Column Cartridge, 2/pk with Holder

Suitable in Either Reversed Phase or Normal Phase Mode. Shim-pack GIS CN is capable of either normal phase or reversed phase analysis. Cyanopropryl groups bonded to silica gel with high density increases the difference recognition of hydrophilicity and the tability. Due to no end-capping, it is capable of analysis utilizing cyano group characteristics. In reversed phase mode, separation can be achieved for those compounds that could not be separated on straightchain-alkyl columns, such as C18 or C8 bonded phases. When using the column for reversed phase mode, fully equilibrate the column before use. Bonded Phase Cyanopropryl Group, Particle Size 3 ?m, 5 ?m, Pore Size 10 nm, Surface Area 450 m2/g, Carbon Loading 14 %, End-capping No, pH Range 2 to 7.5,USP Code L10.
