CHROMABOND® XTR

 

Kieselguhr phase for liquid-liquid extraction

 

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

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.
Eluents with too high alcohol contents cause an increase in volume of the aqueous phase on the CHROMABOND® XTR. Here the column could be overloaded and the aqueous phase displaced from the column. In this case, a greater capacity column should be used.
