AQ is associated with "Aqua". To meet the recent demand for analysis of high-polarity compounds, this column provides excellent reproducibility in a 100% aqueous mobile phase that was previously considered impossible. AQ is intended for use under mobile phases of low organic content.
Hydrophobicity and surface polarity parameters of Shiseido columns
AQ for analysis of high-polarity compounds!
AQ ensures excellent retention and separation for high-polarity compounds. Basic compounds show good peak shapes free from tailing. This column can also handle a mobile phase of 100% water that previously posed reproducibility problems for conventional ODS.
Excellent retention of polar compounds
AQ with extremely high surface polarity, featuring excellent retention of polar compounds among the CAPCELL PAK Series
Extremely symmetrical peak shapes of basic compounds
Free from tailing due to the synergetic effects of polymer coating and elaborate end capping
Mobile phase of 100% water available
Avoiding so-called "phase collapse" of ODS by reducing the bonding density of ODS groups in silica gel
Excellent durability
Polymeric and polymer coating for excellent acidic resistance as well as basic resistance and for stable use in the pH range 2-9
Ultra-low pressure and large number of theoretical plates
Amazingly low pressure and large number of theoretical plates in not only 5-m but also 3-m packing material by the use of narrow size distribution silica
Full range of column sizes
A complete lineup from microcolumns of 0.3 mm i.d. to LC-MS fast columns 20 mm long and semi-aliquot columns
