Drying / Evaporation / Concentration

Evaporation is a key step in the analytical process and Horizon Technology offers several ways to accomplish this. Our application notes describe features and performance of the systems. Recoveries of the analytes balanced with rapid evaporation is the goal and this is achieved for many classes of compounds.

The DryDisk Separation Membranes offer a much more efficient means of drying solvents in organic extractions than sodium sulfate. Because it is a physical separation rather than a chemical process to remove residual water from organic solvent extractions, DryDisk membranes eliminate the problems inherent with chemical drying, messy water removal, and inability to handle emulsions. When used in combination with the DryVap system, the sample drying and concentration phase of the extraction process is a breeze.
