With Raptor LC columns, Restek chemists became the first to combine the speed of 2.7 and 5 \u03bcm superficially porous particles (also known as SPP or \u201ccore-shell\u201d particles) with the resolution of highly selective USLC technology, improving separations and speeding up analysis times with standard HPLC instruments. Raptor then evolved to bring that same improved speed, efficiency, and selectivity to UHPLC analyses by offering 1.8 \u03bcm particle columns.

Our top priority when developing our SPP line was to create a version of our innovative Biphenyl. The industry-leading Biphenyl is Restek\u2019s most popular LC stationary phase because it is particularly adept at separating compounds that are hard to resolve or that elute early on C18 and other phenyl chemistries. As a result, the rugged Raptor Biphenyl column is extremely useful for fast separations in bioanalytical testing applications, such as drug and metabolite analyses, especially those that require a mass spectrometer (MS). Increasing retention of early-eluting compounds can limit ionization suppression, and the heightened selectivity helps eliminate the need for complex mobile phases that are not well suited for MS detection.<\/p>\n\n\n\n

In 2005, Restek was the first to bring you the benefits of the Biphenyl ligand, and we have the experience to maximize the SPP performance of this premier phenyl chemistry for today\u2019s challenging workflows.<\/p>\n\n\n
