Product details

Material: PP with special membrane.

You replace the complex liquid-liquid extraction (LLE) with solid-liquid extraction (SLE).
These columns guarantee a far greater yield and better reproducible extraction process, from column to column, when compared to historical liquid/ liquid extraction techniques usually using water and an organic solvent into a conventional separation funnel.

  • Fast and effective sample preparation technique
  • Higher reproducibility and recovery rates compared to LLE methods
  • No problems with phase boundaries - Prevents the emulsion formation that often occurs in LLE, since the water-immiscible solvents do not come into direct contact with the sample
  • Reduced solvent requirements compared to LLE

Automatic separation of a two-phase mixture without separation funnel. Two-phase mixtures are completely applied to the column and the phase boundary is determined without further work. The special membrane automatically stops the flow when the lower phase has passed. The upper phase remains in the column, thus both phases are available for futher analysis.Important note: Columns must not be run with vacuum or pressure. SPE columns for phase separation by gravity only.

General information

Eluents with higher alcohol contents cause an increase in volume of the aqueous phase on the CHROMABOND® XTR. In such case, the column might be overloaded which leads to a displacement of the aqueous phase from the column. Therefore a greater capacity column should be used.

Extraction of analytes form an aqueous to an organic phase:

Column conditioning: Not required

Sample application: Aqueous solutions are applied to the dry CHROMABOND® XTR adsorbent. They are soaked up by the solid within a few minutes and spread over the surface of the kieselguhr material as a thin film.

Elution: Lipophilic analytes are eluted with water-immiscible organic solvents; the aqueous phase remains on the CHROMABOND® XTR adsorbent. Polar, water-soluble analytes, which remain in the aqueous phase on the XTR adsorbent, can be eluted e.g. with saturated NaCl.

Warning: Never exceed the volume capacities listed for each column size!

Solvents applicable for elution:

Diethyl ether (T900)
tert-Butyl methyl ether (T175)
Ethyl acetate (T164)
n-Hexane (T165)
Cyclohexane (T163)
Toluene (T166)
Dichloromethane (T901)
Trichloromethane (chloroform) (T901)
Trichloromethane/methanol (90/10 or 85/15, v/v) (T901/T909)
Diethyl ether/ethanol (90/10 or 80/20, v/v) (T900/9065)
Dichloromethane/2-propanol (90/10 or 85/15, v/v) (T901/T902)

General column parameters:

Depending on the concentration of the analytes eluates can be analysed immediately, or the organic solvent is evaporated. The pH value of the aqueous solution can be altered on the column, which enables elution of different compounds of a sample under optimised conditions. Under certain circumstances, acidic, neutral, and basic compounds can be fractionated in this way.
