Discovery Zr-Carbon

by Sigma Aldrich

Discovery® Zr-Carbon HPLC Column
3 μm particle size, L × I.D. 15 cm × 2.1 mm
 
Discovery Zr-Carbon HPLC columns
Features and Benefits

  • Excellent separation of geometric isomers and diastereomers.
  • Very hydrophobic surface.
  • Most different retention compared to other Discovery Zr phases for non-ionic compounds.
  • Similar to porous graphitic carbon, but with added ion-exchange interactions.

Discovery Zr-Carbon comprises spherical, porous carbon-coated zirconia particles. It is ideal for the reversed-phase separation of positional isomers and diastereomers. It complements the selectivity offering of the other zirconia- and silica-based Discovery phases, and allows the use of the full range of mobile phase pH from pH 1 to 14. It is a great alternative when C18 does not work.
