Primesep 200 separates the very hydrophilic polyamines, 1,3-diaminopropane, N-(3-aminopropyl)-1,3-diaminepropane, N,N-bis-(3-aminopropyl)-1,3-diaminepropane. The retention and resolution are affected by either a TFA concentration gradient, or a pH gradient from pH 4 to 3. This flexibility is obtained by simple mobile phases of water, acetonitrile (MeCN, ACN), ammonium formate, ammonium acetate or trifluoracetic acid (TFA) with evaporative light scattering detection (ELSD).
The Primesep family of mixed-mode columns offer a wide variety of stationary phases with an unprecedented selectivity in the separation of a broad array of chemical compounds and in multiple applications. Corresponding Primesep guard columns are available with all stationary phases and do not require holders. SIELC offers a method development service which is available for all customers.
