Shim-pack GIST Phenyl, 3um, 2.1 x 50mm LC Column

The GIST Phenyl column with its multiple retention mechanisms can separate a wide variety of compounds. These include aromatic compounds (through pi-pi interaction) that have little to no retention or poor resolution on traditional alkyl phases like C8 and C18, and structural isomers through stereoselectivity since the phenyl groups are directly bonded to the silica particle. USP L11, pore size: 100A, surface area: 350 m2/g, 10% carbon load, pH range: 2 to 7.5. A guard column is recommended to prolong the lifetime of the analytical column. Similar to Premier C18 220-91199-45.
