Enricher for Fraction of High-Pressure Liquid Chromatography [PDF]
Journal of Chromatographic Science, 2005 A device is developed for concentrating a dilute solution without losing the components with boiling points slightly higher than the solvent. The device consists of an evaporator, receptor, and approximately 100 capillaries. A dilute solution is introduced into the evaporator and heated at a lower temperature than the boiling point of the solvent with ...
