Zirconia Based HPLC Columns

Zirchrom Zirconia Based HPLC Columns

PBD (USP L49)

  • Great peak shapes for basic compounds
  • A reversed-phase like material, but with slightly different selectivity. Stable from pH 1-14
  • Not as hydrophobic as typical C18-silica phases, so less organic solvent is required
  • Selectivity is modifiable through the addition of a strong Lewis base to the mobile phase such as fluoride, phosphate or hydroxide

CARB

  • Quality comparable or better than HypercarbTM at a lower price
  • Very different selectivity than ODS or polymeric materials; a good alternative when ODS does not work
  • Better for geometrical isomer separations than ODS or normal phase LC
  • Superb for separating diastereomers

C18

  • Ideal for separating steroids and analogues
  • Excellent selectivity for acidic compounds
  • pH stable from 1 – 14 for robust methods
  • Excellent thermal stability for fast separations

WAX (Stable from pH 3 – 9, and to 80 ºC)

  • Cross-linked polyethyleneimine-coated zirconia for weak anion-exchange
  • Efficient weak anion-exchanger useful for inorganic and organic anions
  • Useful for the separation of bio-molecules such as nucleotides, nuceosides, oligonucleotides,oligodeoxynucleotides, amino acids, peptides, and proteins
  • Extremely stable amino phase for normal phase separation of carbohydrates

SAX (Stable from pH 1 – 2, and to 80 ºC)

  • Cross-linked polyethyleneimine-coated zirconia for strong anion-exchange
  • Useful for inorganic and organic anions
  • Ideal for the separation of water-soluble vitamins
  • Useful for the separation of bio-molecules such as nucleotides, nucleosides, oligonucleotides, oligodeoxynucleotides, amino aicds, and peptides.
