INTRODUCTION
This application shows very nice peek symmetry and separation of aromatic amines in a Engelhardt mixture.
ABSTRACT
Isocratic HPLC/UV separation of aromatic amines in an Engelhardt test mixture – aniline (CAS 62-53-3), 4-ethylaniline (CAS 589-16-2) and N,N-dimethylaniline (CAS 121-69-7), together with uracil, acetophenone, toluene and naphtalene – on an ASTRA® C18-BDS, 5 µm column (150 mm × 4.6 mm, AST-5875-LK46). Isocratic elution with water:ACN (45:55) at 1 mL/min and 25 °C, injection volume 1 µL, UV detection at 254 nm. All seven components are resolved within about 9 minutes with very good peak symmetry.
