Raptor™ C18 LC Columns (USP L1) by Restek Corp.
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 without expensive UHPLC instrumentation.
Every LC lab has a cache of C18s, but every C18 is not created equal. Because the chemistry tends to be similar, the silica support that carries this... Read more
