Used in normal or reversed phase, extracting polar compounds

 

Diol is a dihydroxy bonded silica sorbent similar to un-bonded silica sorbent in its capabilities. In addition to its normal retention resulting from strong hydrogen bonding with analytes, the hydrophobic spacers of its functional groups serve to reversed phase retention to a certain extent.Diol is an alternative to un-bonded silica sorbent if the latter’s strong acidity leads to retention of basic interferences.

 

Features:

  • Capable of polar and non-polar retention
  • Similar to un-bonded silica sorbent in its capabilities
  • Reduced retention of basic interferences

 

Specifications:

Carbon content: 5.5%
Surface area: 290 m 2/g
Particle size: 40 - 75 μm
Pore size: 100 Å

 

Applications:

  • Analysis of phenols, pigments and phospholipids in plant oils
  • Determination of drugs and their metabolites in biological fluids such as urine
  • Separation of glycan mixtures
