• Ideal for bioanalytical testing applications like drug and metabolite analyses.
• Heightened selectivity and retention for compounds that are hard to resolve or elute early on C18 and other phenyl chemistries.
• Limits ionization suppression and allows simple, MS-friendly mobile phases.
• Part of Restek’s Raptor LC column line featuring 1.8, 2.7, and 5 μm SPP core-shell silica.
