HALO® ES-CN Capillary
HALO® ES-CN Capillary HPLC Columns from AMT
HALO 90 Å ES-CN is moderately polar in nature and highly suited for the separation of acids, bases, and neutrals. It will often exhibit different selectivity compared to straight-chain alkyl phases, such as C8 and C18.
The sterically protected, extensively endcapped diisopropyl-cyanopropylsilane stationary phase of HALO 90 Å ES-CN provides a stable, reversed-phase packing that can be used for basic, acidic or neutral compounds.
- Complementary selectivity to alkyl phases
- More retention for polar analytes and much less retention for non-polar analytes
- Target analytes are polar and very polar bases, acids and neutrals
- Example applications are explosives, aromatics and polar compounds
