OCHRAKING

Overview

OCHRAKING, is an IAC which effectively cleans up Ochratoxin.

Features

High organic solvent-tolerance– efficient test and pretreatment

 

 

 

  • Cleans up Ochratoxin with only a small quantity of extract.
  • Saves significant pretreatment time and increases the analysis efficiency.
  • Purifies Ochratoxin A and B,
  • Accepts ammonium acetate solution and purified water for washing columns.

 

OCHRAKING improves the efficiency of sample clean up.

Its high organic solvent tolerance enables rapid clean up with only a small quantity of sample solution.

Recovery test/wheat

Ochratoxin in wheat is analyzed by extraction with 60% acetonitrile and diluting the extract with PBS to 30% for cleaning up Ochratoxin A and B.  When only analyzing Ochratoxin A, acetonitrile concentration of up to 48% is used.
