Dionex™ ASE™ Prep DE

Designed for use with Thermo Scientific™ Dionex™ ASE™ Accelerated Solvent Extractor systems, Dionex ASE Prep DE dispersant is pelletized diatomaceous earth that acts as a dispersant and drying agent. The material is mixed with the sample prior to adding the sample to an extraction cell. It can also be easily mixed with Dionex ASE Prep MAP in a 1:1 ratio for optimum moisture removal under accelerated solvent extraction conditions.

Dionex ASE systems automate extraction, filtration, and clean-up of solid and semisolid sample matrices using common solvents at elevated temperatures and pressures. Low- and high-throughput systems are available for a wide variety of applications.

Dionex ASE systems enable extraction of sample sizes 1-100g in minutes, perform unattended extraction of up to 24 samples, and use 50–90% less solvent compared to other methods. The chemically inert pathway supports acidic and alkaline matrices and solvents. These flexible, easy-to-operate, cost-effective systems have been approved for use by the U.S. EPA and CLP Program.

There are a variety of products that can be added to the Dionex ASE extraction cell to remove moisture, disperse the sample matrix, and neutralize mineral acids.
