Shim-pack GIST (G) Phenyl-Hexyl, 5um 4.0 x 10mm LC Guard Column Cartridge, 2/pk with Holder

Column, LC, Shim-pack GIST Guard Phenyl-Hexyl, 5um 4.0x10 with Cartridge (2pcs) and Holder Alternative Selectivity to C18 Columns Shim-pack GIST Phenyl-Hexyl columns are bonded with a phenyl ring together with a hexyl (C6) chain, which provides complementary selectivity to straight alkyl-chain columns due to its ?-? interactions and hydrophobic interactions. Furthermore, Shim-pack GIST Phenyl-Hexyl maintains the same ultra-high inertness, wide pH range and high durability as the Shim-pack GIST C18, achieving stronger retention than other phenyl columns as well as reducing or eliminating adsorption of polar compounds.
