👉 Flensing, also known as flensing or flensing process, is a method of distillation used in chromatography. It involves heating a sample to a temperature below the boiling point of the solvent, and then adding a substance that will condense on the surface of the solvent at the same temperature. This allows the solvent to be separated from the material being analyzed by changing the temperature. Flensing is commonly used for separation of organic compounds in chromatography because it can separate volatile substances from their components
