Epic Phenyl Hexyl Sub‐2 Micron ‐ Epic Phenyl‐Hexyl Sub‐2 Micron uses a hexyl‐linked phenyl phase. The hexyl alkyl chain provides for unique selectivity and increased hydrolytic stability when compared to propyl‐linked chemistry. The Epic high‐density bonding technology delivers to the chromatographer superior performance, durability, and enhanced lot‐to‐lot reproducibility. Epic Phenyl‐Hexyl Sub‐2 Micron offers the chromatographer a truly superior phenyl based interaction for enhanced chromatographic performance. A chromatogram containing a rapid baseline separation of a mixture of Nitroaromatics is shown below. This mixture is difficult to separate on a typical phenyl type column.
