Pervaporation as an Alternative to Headspace

Analytical Chemistry, 1997
The use of pervaporation as an alternative to headspace is proposed. The analytical system involves the speciation of organomercury compounds in solid samples using pervaporation, which has been coupled for the first time to gas chromatography. The speciation of mercury as Me(2)Hg, Et(2)Hg, and MeHgCl has been carried out without any derivatization of ...

Pervaporation in chemical analysis

Journal of Chromatography A, 2010
Unlike thermal processes such as distillation, pervaporation relies on the relative rates of solute permeation through a membrane and is a combination of evaporation and gas diffusion. The analytical pervaporation systems consist of a membrane module suitable for liquid sample introduction and a vacuum (or a sweeping gas) on the permeate side.

The Use of Pervaporation in Biotechnology

1993
One of the major problems in modern industrial scale biotechnology is the separation, concentration and purification of the bioreaction products. This mass separation task, generally referred to as ‘downstream processing’, is often particularly difficult.

Pervaporation with Latex Membranes: A Study on Membrane and Pervaporation Effects

Separation Science and Technology, 1995
Abstract The separation process is affected by a number of factors related to the membrane itself and the operation conditions. For latex membrane systems, factors such as feed concentration and feed temperature are found to affect pervaporation properties similarly to solvent-cast membrane systems.

Enantioenrichment by pervaporation

Journal of Membrane Science, 2004
The present paper describes an original concept of membrane-assisted enantiomer enrichment exploiting a combination of complexation to β-cyclodextrin and selective transport through a PDMS pervaporation membrane. Linalool has been used as a model racemic mixture, due to its large use in perfumes, soaps and detergents. Results, under different operating
