HPLC Separation of Polyamines

HPLC Separation of Polyamines

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).
