Restek Unleashes Superior Raptor Performance on Your UHPLC Analyses — Now with 1.8 μm Particles

Raptor LC columns have been providing higher efficiencies, faster analyses, and rock-solid reliability to HPLC users for several years.

And they have just evolved again.

Restek has brought the benefits of Raptor columns to those who have made the leap to UHPLC instruments, yet are still looking to boost their efficiencies further. Already sold with 2.7 and 5 μm superficially porous particles (SPP), Raptor columns are now available with 1.8 μm particles specifically for use with UHPLC. Choose from four distinctive Restek phase chemistries: Biphenyl, ARC-18, C18, and FluoroPhenyl.

Raptor 1.8 μm columns are designed and QC tested for maximum lifetime under UHPLC pressures. And, because they are Raptor SPP LC columns, they offer the peak capacity, selectivity, and reproducibility that analysts have learned to depend on from Restek.

About Raptor SPP LC Columns:
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. Raptor LC columns provide the practicing analyst with the most powerful tools available for fast, efficient method development and increased sample throughput. And, because they are from Restek, Raptor LC columns are backed by manufacturing and quality systems you trust along with internationally renowned Plus 1 service.
