Separation processes, like liquid-liquid extraction play an important role in pharmaceutical and chemical industries. Nano membranes are used to separate organic solvents from valuable substances, that were produced by organic synthesis. The organic solvents can be used for further syntheses. That saves a lot of money and has positive environmental effects. Schmidt + Haensch provides the technology for monitoring those separation processes. Our precision instruments can detect even smallest amounts of unwanted substances in both, the organic solvents and the product.
