The Raptor Biphenyl provides increased retention and selectivity (especially when using methanolic mobile phases) for compounds that are hard to resolve, or elute early on C18 and other phenyl chemistries. Ideal for bioanalytical testing applications over a wide range of compound classes including steroids, benzodiazepines, antidepressants, and many more, as well as bisphenols, explosives, synthetic cannabinoids, and pharmaceuticals and personal care products (PPCPs.)
