The C4A\u2010mPEG capillary column, prepared by the static coating method, showed moderate polarity and a column efficiency of 2332 plates\/m, determined by 1\u2010octanol at 120\u2009\u00b0C. The separation features of C4A\u2010mPEG stationary phase, resulting from its unique structure and multiple molecular recognition processes with analytes, including <jats:italic>\u03c0\u2010\u03c0<\/jats:italic>, H\u2010bonding, dipole\u2010dipole, and van der Waals interactions, allowed to obtain high\u2010resolution performances for a wide range of compounds and their isomers, especially benzaldehydes, phenols, and anilines. Moreover, compared with 4\u2010tertbutyl calix[4]arene (C4A) and polyethylene glycol (PEG) stationary phases, a higher resolving capability was also observed for the separation of toluidine and xylidine isomers.<\/jats:p>","DOI":"10.1002\/cbdv.202200829","type":"journal-article","created":{"date-parts":[[2022,11,14]],"date-time":"2022-11-14T03:25:42Z","timestamp":1668396342000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A New Capillary Gas Chromatography Column Based on Poly(ethylene glycol) Methyl Ether\u2010Functionalized Calix[4]arene"],"prefix":"10.1002","volume":"19","author":[{"given":"Ruonan","family":"Chen","sequence":"first","affiliation":[{"name":"Liaoning Province Professional and Technical Innovation Center for Fine Chemical Engineering of Aromatics Downstream School of Petrochemical Engineering Shenyang University of Technology  Liaoyang 111003 Liaoning P.
