Polymer Analysis Utilizing Psuedo 2D Liquid Chromatogram Integrated with LC-ESI-MS Data Using Two Different Columns

A simple and rapid method to provide a 2-dimensional liquid chromatogram (LCxLC) was developed for the characterization of synthetic polymers using liquid chromatography coupled with electrospray ionization mass spectrometry (LC-ESI-MS). Two sets of LC-MS chromatogram data using two different LC columns were prepared in property. The elution time of each chromatogram was plotted based on ions with the same m/z values, to give a scattering diagram of pseudo 2D-chromatogram. The application of this method was discussed to separate and identify a mixture of ten different polyethers.
