Abstract: This support is constituted by a crosslinked polyvinyl alcohol hydrogel, whereof at least part of the --OH groups have been replaced by --OSO.sub.3 H groups. The crosslinked polyvinyl alcohol hydrogel comprises 70 to 95% by weight of chains derived from polyvinyl alcohol and 5 to 30% by weight of chains derived from crosslinking monomers, such as triethylene glycol diacrylate and tetraethylene glycol triacrylate.These supports can be used for the ex-vivo purification of the blood plasma in pocket 31 or 33.

Abstract: To elute fluorinated emulsifying acids, especially perfluoro-carboxylic acids, from basic anion exchangers a mixture of dilute mineral acid and polar organic solvents is used. The solvent should be miscible with water preferably to an extent of at least 40%. By this process the required amount of eluent and the time of elution can be reduced while simultaneously the amount of recovered emulsifying acid can be improved. The process is especially suitable for the recovery of fluorinated emulsifiers in the coagulation or concentration of fluoropolymer latices.

Abstract: This invention relates to a method for the separation of low molecular-weight aromatic compounds, e.g. vanillin and dehydrodivanillin, from lignin, alkali, and from each other, in alkaline aqueous solutions. According to the method, the separation is effected by means of a cationic ion-exchange resin in its sodium salt form, e.g. of a strong sulphonic acid type or weak carbonic acid type, from which the substances adsorbed are removed by elution. The resin may be crosslinked to the extent of 2-16% divinylbenzene. The substances adsorbed onto the ion-exchange resin are appropriately eluted by either water alone, or by application of an aqueous sodium-salt solution (e.g. Na.sub.2 CO.sub.3) followed by water.

Abstract: This invention relates to an ion exchange column for the removal of bacteria from a liquid medium wherein the column has, as an indicator to indicate when the column capacity for removal of bacteria is exhausted, a filter having submicron pores which will become plugged after a short period of usage with an exhausted bacteria-removing ion exchange column so that pressure build up will noticeably reduce the flow of liquid exiting from the filter thereby indicating to the user that the ion exchange column is exhausted. This invention also relates to a process for removing bacteria from a liquid medium wherein a bacteria containing medium is passed through an ion exchange column capable of removing such bacteria and then through a filter having submicron pores. When the capacity of the ion exchange column for removing bacteria is substantially exhausted, bacteria are removed by the submicron filter which quickly plugs. The build up in pressure, as a result of the plugging of the submicron filter, results in a reduction in the flow of liquid exiting from the filter and thereby indicates to the user that the ion exchange column has become exhausted for its intended purposes.

Abstract: Microporous anionic exchange and non-ionic adsorbent resins which are capable of adsorbing an antibiotic and which have been coated with a non-ionic detergent are disclosed. When contacted with bacterially infected body-fluid specimens, the disclosed resins remove antibiotics from the specimen while exhibiting diminished bacterial adsorption. A combination of a disclosed detergent-coated non-functional adsorbent resin with a cationic resin removes other bacterial inhibitors, as well as antibiotics, from bacterially infected body fluid specimens while permitting the bacteria to remain in the specimens. By removing bacterial inhibitors while sparing the bacteria, the disclosed resins make possible rapid isolation and identification of an infecting organism.
