Maleic aid

Primesep A separates acids, bases, and neutrals in one injection. Maleic acid, benzonitrile, and benzylamine are baseline resolved by a combination of reversed-phase, ion-exchange, and ion-exclusion mechanisms. Excellent peak shape results with a mass spec compatible mobile phase of water, acetonitrile (MeCN, ACN) and trifluoracetic acid (TFA) with UV detection at 210 nm.
