Zwitterionic hydrophilic interaction chromatography

Zwitterionic hydrophilic interaction chromatography (ZIC-HILIC) has also been used as a method of separating DPAA and PAO [42]. This separation technique relies on a partitioning mechanism between the mobile phase (high... [Pg.126]

Figure 4.11 Separation of nine different organoarsenicals including PAO (peak 1) and PAA (peak 2). (a) Isocratic separation with 78% acetonitrile and (b) gradient separation with 78-70% acetonitrile. ICP-MS and ES-IMS were used in parallel for elemental and molecular identification [42]. D.

Hydrophilic interaction chromatography (HB IC) or aqueous normal-phase chromatography (ANP) refers to the use of polar stationary phases (e.g., bare silica, silica, or polymeric phases with bonded zwitterionic ligands, diol phases) in combination with a mobile phase rich in organic solvent but containing a significant amount of water (typically at least 3%). Bell [97] summarized the advantages of this technique as follows ... [Pg.344]
