|Use:||Relatively new and simple technique for extracting contaminants from water.|
Membrane extraction uses extractant fluids containing organic solvents, such as hexane, flowing through a tubular silicone rubber membrane to selectively extract and concentrate organic compounds of interest from a sample flowing outside the tube. In its simplest application, extractant fluid flows directly to the analytical instrument for analysis. For more complex samples, additional separation steps might be required.
