Abstract:
The supercritical fluid chromatography coupled with mass spectrometry (SFC-MS) method and liquid chromatography coupled with mass spectrometry (LC-MS) method were developed for the separation and characterization of poly (ethylene oxide) methyl glucose sesquistearate (PEO-Glu-sesquistearate). The products of PEO-Glu-sesquistearate are composed of complex oligomers. The relationship between molecular structure of these oligomers and chromatographic retention behavior in both SFC and LC were discussed and compared. As compared with LC, hydrophobic moieties of compounds favor the fast elution in SFC. The different series can be better separated by LC, while the homologues compounds in same series can be better separated by SFC, and SFC-MS provided more comprehensive structural information. Different series such as PEO-distearate, PEO-stearate, PEO, PEO-Glu-tetrastearate, PEO-Glu-tristearate, PEO-Glu-distearate, PEO-Glu-stearate, and PEO-Glu were identified by MS/MS.
