Abstract

Microcolumn (250x0.5 mm I.D.) size-exclusion chromatography was implemented for the separation of polydisperse mixtures prior to electrospray ionization (ESI) mass spectrometric detection. An improved separation, compared to conventional-bore SEC, was demonstrated upon coupling with ESI quadrupole ion-trap mass spectrometry and a Fourier transform ion cyclotron resonance instrument for the separation of individual oligomers present in octylphenoxypoly(ethoxy)ethanol.
