Raptor C18, 1.8 µm, 150 x 2.1 mm HPLC Column

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times with existing HPLC and UHPLC instrumentation.

When you need a general-purpose LC column, don’t just grab any C18. Choose the speed, efficiency, and long-lasting ruggedness of the Raptor C18 column. This traditional end-capped C18 offers the highest hydrophobic retention of any Raptor phase, and it is compatible with a wide range of mobile phases from moderately acidic to neutral (pH 2–8). Whether for food safety or environmental or bioanalytical analyses, this phase offers consistently excellent data quality in less time across myriad reversed-phase applications, matrices, and compound classes. To lower costs and improve profitability, you need columns to last longer, data to be reproducible, and existing HPLC and UHPLC instrumentation to run faster. Get there with the only general-purpose C18 that gives you Selectivity Accelerated.
