Removal of interferents in analytical assays in a two phase interferent- removal zone

摘要

Novel elements for the analysis of liquids which contain interferents for an analyte assay are described. Interference is reduced in multizone elements by the presence of an interferent-removing zone between the point of introduction of the liquid and the assay-indicator zone wherein the interferent- removing zone comprises a discontinuous phase within a continuous phase. An interferent-removing material is present in the discontinuous phase and the continuous phase is permeable to the analyte, its products and/or the liquid being analyzed.
