In addition to enabling chromatographers to run in reversed-phase or HILIC mode for various compounds, Raptor™ FluoroPhenyl column is amenable to LC-MS due to its reliability and efficiency regarding acidic mobile phases. Design combines speed of superficially porous particles (SPP or core-shell particles) with resolution of highly selective USLC® technology. Chromatographic column allows users facilitated means of achieving peak separation and accelerated analysis.
