The present invention relates to an electrolyte solution comprising at least one solvent as component A, at least one electrolyte as component B and from 0. Detection involves the release of identifying tags as a consequence of target recognition. The firing rod is disposed at least partially with the elongate portion and is proximally and distally translatable with respect to the elongate portion. These blending constituents are combined to provide an optimized transfer characteristic function. 5 weight-percent as measured at half peak height of a copolymerized acrylonitrile comonomer distribution curve for the styrene-acrylonitrile copolymer.
