Separation of Propylendiamine 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). Application Analytes: 1,3-Propanediamine N-(3-Aminopropyl)-1,3-propanediamine N,N'-Bis(3-aminopropyl)-1,3-propanediamine Polyamines Propylendiamine Application Detection: UV Detection |
