S-Layer Ultrafiltration Membranes

Ultrafiltration through Collodion Membranes

It is obvious that the factors considered in this paper render data obtained by ultrafiltration open to criticism unless they are checked by other methods and precautions are taken for the elimination of the vitiating effects which have been described. As regards the mechanism of ultrafiltration, the view of a sieve-like action as most experimental evidence indicates, is adequate, if all the fa...

Novel Charged Ultrafiltration Membranes for Protein Separations

Although there have been no significant studies of the effects of different coupling chemistries, spacer arm length, or the nature of the functional group on the performance of ultrafiltration membranes, there is an extensive literature on these parameters in the field of chromatography. An optimal spacer arm ensures that the functional groups are placed a suitable distance from the surface of ...

Characteristics of Collodion Membranes for Ultrafiltration

An apparatus for the production of graded collodion membranes is described. The theoretical considerations of calibration are discussed in relation to the demonstrable structure and statistical characteristics of the membranes. A new definition of an "end-point" is suggested.
