DESCRIPTION
			
				Shim-pack Scepter columns consist of an organosilane hybrid particle for excellent stability and performance.  The phenylbutyl ligand provides unique selectivity compared to a C8 or C18  due to pi-pi interactions between the analyte and stationary phase.  The phenyl phase is recommended for the analysis of aromatic compounds, isomers and structural analogs, and can be used in 100% aqueous conditions.   USP L11, pore size: 120A, pH range: 1-10, max pressure:  100 MPa/1000 bar/14,500 psi, 17% carbon load, fully endcapped.  A guard column is recommended to prolong the analytical column lifetime.  Similar to Acquity BEH Phenyl.
