The Raptor C18 is a traditional endcapped C18 column for general-purpose use. The superficially porous particle (SPP) provides UHPLC-like resolution with standard LC systems. Ideal for high-throughput applications with large analyte lists including DNPH-derivatized aldehydes and ketones, veterinary drugs, and perfluorinated compounds (PFCs.) USP L1, pore size: 90A, surface area: 125m2/gram, carbon load: 9%, non-endcapped. pH range: 2.0 - 8.0, maximum temperature: 80C, maximum pressure: 103 MPa/1034 bar/ 15,000 psi. NOTE: for maximum lifetime, recommended maximum pressure is 83 MPa/830 bar/12,000 psi.
