Sample Prep Made EasierAccelerated Solvent Extraction (ASE®) with In-Cell Clean-Up by DionexASE systems are designed to combine important sample prep tasks such as extraction, filtration, and clean-up, to streamline the sample preparation process. Flow-through extraction allows absorbents to be added directly to the ASE extraction cell to remove interferences, for one-step extraction and clean-up. 
- May eliminate GPC or other post-extraction clean-up steps.
- Reduces process time by performing clean-up and extraction simultaneously.
- Increases total sample preparation throughout – not just the number of samples extracted.
Absorbents for use in removing interferences from specific analyte groups include: Absorbents | Interferences | Analyte Group |
| Carbon | Organics | Non-polar compounds, dioxins |
| Copper | Elemental sulfur | Multi-residue pesticides |
| Ion-exchange resins | Organics, metals and ionic interferences | Anions, cations, metal speciation (arsenic) |
| C18 resins | Organics, lipids, chlorophyll | Non-polar compounds |
| Acid impregnated silica gel | Lipids and oils | PCB and bromated flame retardants |
| Alumina | Lipids, chlorophyll, petroleum, waste | Amines, perchlorates, and PCB’s |
| Florisil™ | Oils, lipids, and waxes | Pesticides and aromatics |

ASE with in-cell clean-up can reduce your sample preparation time while minimizing errors and analyte loss. - Minimize labor
- Reduce sample handling:
- Minimize transfer errors.
- Reduce analyte loss due to quantitative transfers.
