Dionex offers products that can be added to the ASE^® extraction cell to remove moisture, disperse the sample matrix, and neutralize mineral acids.

ASE Prep DE
ASE prep DE is pelletized diatomaceous earth that acts as a dispersant and drying agent. This is mixed with the sample prior to adding the sample to an extraction cell.

ASE Prep CR
ASE prep CR is a cation-exchange resin in sodium form that neutralizes strong mineral acids that may have been used as a pre-treatment for acid hydrolysis of solid samples.
