C8 Column Zodiac C8 Column, An excellent resolution for critical separations, faster analysis compared to C18 increased selectivity, exceptional reproducibility. Zodiac C8 Column is an admirable choice for separations that need marginally more polar phase than C18. The high surface area that is about 440m2/g in Zodiac C8 column provides additional resolution to polar phase. Zodiac C8 column is less hydrophobic column with high surface area, optimal carbon load and unique bonded silica packing. C8 Column This column is ideal choice when analytical laboratories need extra selectivity and more speed than the C18 column. The superior resolution of Zodiac C8 yields out and out separation first time, speeding up method development and validation. These columns are highly stable and produce ever reliable results with an extended column life. The column comes with protective end-capping for a better peak without tailing and high durability of column. Faster, sharp and reproducible responses ar...

Phenyl Column Phenyl Column ü Extraordinary resolution ü Excellent choice for separating mixture of polar and non polar analytes ü Superior selectivity of structurally comparable compounds Employing ultra pure, higher stability silica and unique bonding technology, Zodiac-Phenyl columns are exceptionally designed to ensure maximum performance. Zodiac- Phenyl columns contain carbon load of about 15.0% which gives best required retention. The silica phase packing and end capping of column is completely controlled, that ensures column-to-column reproducibility. The uniform ultra pure silica particles have high surface area of 440m2/g with a controlled pore size of 100Å. Zodiac-Phenyl columns show great selectivity and peak symmetry with fairly high retention for separation of mixtures of polar and non polar compounds. The pi-pi interactions in the phenyl stationary phase influence the solute pi electrons which causes ultimate separation of compounds containing isomers. The column is conve...
