| Abstract: | A styrene/divinylbenzene polymer column and an amino column are compared for the non-aqueous separation of primary, secondary and tertiary alkylamines. Post-column derivatization with o-phthalaldehyde/2-mercaptoethanol is selective for primary amines and derivatization with 7-chloro-4-nitrobenzo-2-oxa-1,3-diazole (NBD-Cl) is selective for secondary amines after on-line masking of primary amines. This procedure can tolerate 0.4 M butylamine. The limit of detection is 18.5 mM for dioctylamine (with NBD-Cl) and 0.18 mM for decylamine and tetraethylenepentamine (with o-phthalaldehyde/2-mercaptoethanol). |
