Abstract
Official abstract text for this publication.
An aqueous liquid medium for analyzing, purifying or separating species in an element having walls or for treating the walls of an element. The medium includes at least a polymer consisting of several polymeric segments. The polymer is of the irregular block-copolymer or irregular comb-like polymer type and has on the average at least three junction points between polymeric segments of different chemical or topological nature. The medium may be used in methods for analyzing, purifying or separating species and methods for treating an element to be contacted with a fluid and/or species contained in the fluid during preservation, transport, analysis, purification or separation of the fluid.
First claim
Opening claim text (preview).
The invention claimed is: 1. An aqueous liquid medium for analyzing, purifying or separating species inside an element comprising walls or for treating the walls of said element, comprising: at least one polymer having several polymer segments that differ in chemical or topological nature, said at least one polymer being one of: (a) an irregular block copolymer and (b) an irregular comb polymer having a polydispersity of at least 1.5 for all polymer segments of at least one chemical or topological nature and having side branches with a molecular mass greater than 1500; and a viscosity that does not vary by a factor of 2 or more over a temperature range of 20° C. or less between a temperature that is 10° C. higher than the solidification point of said medium and a temperature that is 10° C. lower than the boiling point of said medium, wherein said at least one polymer has an average of at least three junction points established between polymer segments that differ in chemical or topological nature.
