CHROMABOND SPE Columns, XTR

Key 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

    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

    Recommended 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
