Separation of Epinephrine and Norepinephrine
Primesep 200 separates the catecholamines, norepinephrine and epinephrine, less than 8 minutes. Norepinephrine and epinephrine are baseline resolved by a combination of reversed-phase, and ion-exchange mechanisms. Excellent peak shape results with a mass spec compatible mobile phase of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) with UV detection at 210 nm.
