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
