Description

Use Chromabond™ XTR with Kieselguhr phase for liquid-liquid extraction. Chromabond™ XTR Adsorbent provides options for Chromabond™ XTR columns.

Features

  • Base material coarse-grained kieselguhr (also known as diatomaceous earth, hydromatrix, celite)
  • large pore size, high pore volume, constantly high batch-to-batch quality
  • pH working range 1–13

Application

  • Liquid-liquid extraction of highly viscous aqueous solutions such as physiological fluids (blood, plasma, and serum) in clinical chemistry, dyes in textiles, environmental and food analysis without use of a separation funnel
  • High water loadability without breakthrough of water during elution with organic solvents
  • Also suited for removing small amounts of water from solvents which are not miscible with water

Advantages

  • Fast, reproducible and economical
  • Simultaneous preparation of several samples
  • No problems with phase separation no formation of emulsions
  • High recovery rates
  • Saving of time and solvents
  • Organic solutions need not to be dried after separation

Solvents applicable for elution

  • diethyl ether
  • tert-butyl methyl ether
  • ethyl acetate
  • n-hexane
  • cyclohexane
  • toluene
  • dichloromethane (methylene chloride)
  • trichloromethane (chloroform)
  • solvent mixtures:
  • trichloromethane – methanol (90:10, v/v)
  • trichloromethane – methanol (85:15, v/v)
  • diethyl ether – ethanol (90:10, v/v)
  • diethyl ether – ethanol (80:20, v/v)
  • dichloromethane – 2-propanol (90:10, v/v)
  • dichloromethane – 2-propanol (85:15, v/v)
