LC COLUMNS
Raptor™ SPP Columns
Put Raptor™ LC columns and guards to the test on your most challenging workflows!
Restek is excited to announce the evolution of superficially porous particles with the introduction
of Raptor™ LC columns and guards.
Superficially porous particles (commonly referred to as SPP or “core-shell” particles) changed the world of LC by
dramatically boosting column efficiency and reducing analysis times, but they were only the beginning. With
Raptor™ LC columns, Restek chemists have combined the speed of SPP with the resolution of highly selective
USLC® technology. This new species of chromatographic column allows you to more easily achieve peak
separation and faster analysis times without expensive UHPLC instrumentation.
• Higher efficiency for drastically faster analysis times.
• Better selectivity for substantially improved resolution.
• Increased sample throughput with existing HPLC instrumentation.
• Long-lasting ruggedness for dependable reproducibility.

Dissecting the Raptor™ LC Column
Larger 2 μm Frit
Prevents clogging better than commonly
used 0.5 μm frits; boosts column lifetime
and helps maintain optimal pressures.
Rugged Label
Clearly identifies both flow
direction and column; resists
solvents and tearing to last as
long as your column does.
Proprietary Column-
Packing Technique
Provides greater pressure stability
(600 bar for 2.7 µm; 400 bar for 5 µm);
achieves higher linear velocities without
sacrificing efficiency or lifetime.
Robust 2.7 and 5 μm Particles
Let you run high-speed analyses without UHPLC.
Narrow Silica Distribution
Ensures high efficiency and consistent flows.
Updated Bonding and QC
Guarantee retention time stability, run to run and column to column.
