Chem Elut Cartridges
Chem Elut brings the simplicity of liquid/liquid extraction (LLE) to a disposable cartridge.?Packed with a specially cleaned diatomaceous earth called Hydromatrix, Chem Elut lets you process samples by LLE without the problems of LLE:
- The cartridge format eliminates sample shaking and emulsion formation.
- Solvent flows by gravity only, improving extraction reproducibility.
- The organic extract is automatically separated during the process, allowing for easier automation.
Select the right Chem Elut cartridge based on the total volume of aqueous sample, including any buffers or internal standards:

For extraction of basic compounds, apply samples at a high pH (generally 2 units above the pKa).?For extraction of acidic compounds, apply samples at low pH (generally 2 units below the pKa).?
For added convenience, pre-buffered Chem Elut cartridges are available:
