With Raptor columns, you can speed up method development and enhance sample throughput. It is only possible to fully utilize the efficiency of superficially porous particle technology when it is united with the power of USLC selectivity. Only Raptor LC columns with highly selective USLC stationary phases show shorter retention times and greater resolution. Ordinary superficially porous particles (SPP) with typical stationary phases show shorter retention times than fully porous particles, but still exhibit less resolution. Choose them for all of your valued assays to experience Selectivity Accelerated.įully porous particles with typical stationary phases show longer retention times and less resolution.
And, because they are from Restek, Raptor LC columns are backed by the manufacturing and quality systems you’ve come to trust along with the best Plus 1 service in the industry. Raptor LC columns bond rugged 1.8, 2.7, and 5 µm superficially porous particles with Restek’s unique Ultra Selective Liquid Chromatography (USLC) phases to offer chromatographers the best of both worlds.īy being the first to combine the speed of SPP with the resolution of highly selective USLC technology, Raptor LC columns provide analysts with the most powerful tools available for fast and efficient method development. Selectivity, on the other hand, has a substantial impact on resolution, but shows minimal improvement in analysis times. Although column efficiency, which is boosted with superficially porous particles, considerably accelerates analysis time, it has little effect on resolution (i.e., peak separation). Restek is proud to announce that SPP core-shell technology has evolved with the introduction of Raptor LC columns. Core-shell particles changed LC, but they were only the beginning. As a result, they offer significantly higher efficiency than traditional fully porous particles of similar dimensions. SPP particles feature a solid, impermeable core enveloped by a thin, porous layer of silica that decreases the diffusion path and reduces peak dispersion. Coupled with small-particle technology, SPP also provides an efficiency boost to those running UHPLC when compared to fully porous particles.
This benefit helps customers achieve faster separations with their existing HPLC instruments. The efficiency of superficially porous particles (commonly referred to as SPP or “core-shell” particles) has been proven to provide fast separations with lower back pressures.
