- Solid phase extraction (SPE)
- SPE (LLE/SLE) columns, CHROMABOND XTR, 15 mL/3000 mg
LLE/SLE phase CHROMABOND XTR made of kieselguhr (also known as diatomaceous earth, hydromatrix, celite) for simultaneous preparation of several samples. No problems with phase separation and no formation of emulsions. Organic solutions need not to be dried after the separation. CHROMABOND XTR provides high recovery rates.
