Recent progress in the development, characterization and application of polymeric pseudophases for electrokinetic chromatography

Abstract

This review article details the development, characterization and application of polymeric materials as pseudostationary phases for electrokinetic chromatography over the past two years. Recent developments in cationic polymers and anionic siloxane, acrylamide and polymerized surfactants (micelle polymers) are reviewed. Also reviewed is recent progress in the development and characterization of chiral polymeric phases for chiral separations by electrokinetic chromatography, and application of a polymeric pseudophase with electrospray ionization mass spectrometric detection.

Sensitive chiral analysis by capillary electrophoresis

“…Crown ether: (1) Table 1) [15,18]. Synthetic chiral surfactants have given rise to promising results [19,20] but have the drawback of not being commercially available in many cases.…”

Recent progress in the use of ionic polymers as pseudostationary phases for EKC

“…The current manuscript is the fourth in a series of reviews by this author in this journal [6,7,9], and concerns developments in the area of polymeric PSPs since the previous review in 2004 [9]. The structures of the polymeric PSPs discussed in this manuscript are presented in Figs.…”

Recent progress in the use of soluble ionic polymers as pseudostationary phases for electrokinetic chromatography

“…The introduction and characterization of polymeric PSPs for EKC as well as more recent developments in the area have been reviewed in detail [5][6][7][8][11][12][13][14]. The use of molecularly imprinted polymers (MIPs) in electrochromatography and EKC, including the use of nanoparticle suspensions, has also been reviewed [15][16][17].…”

“…To minimize this limitation, PSPs should have high electrophoretic mobility to provide a wide migration range. Additionally, PSPs should be stable and soluble under a range of analytical conditions such that the retention factor can be adjusted to within a relatively narrow optimum range and should be available with a wide range of chemical structures to provide varied chromatographic selectivity [8].…”
