CHROMABOND® XTR for liquid-liquid extraction
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

Parallel processing of up to 24 CHROMABOND® XTR columns 1 – 150 ml
we recommend the polypropylene rack consisting of
1. Two side walls
2. Middle part including stopcocks and needles
3. Bottom part
4. top part for stabilising 45 ml, 70 ml and 150 ml CHROMABOND® XTR
columns
This rack can be adjusted to various heights depending on the CHROMABOND® XTR columns and the collection vials used. Each position of the middle part is equipped with a polypropylene stopcock on the top and a polypropylene needle on the bottom.
For collection of the sample, vessels such as vials, test tubes, round bottom or tapered flasks, can be used.
