Feb. 3, 1994Sensor devices for detecting components in fluid samples,
especially by electrolytic analytical methods, comprising a detecting
means (usually an anode, especially one of platinum) surrounded by a
selectively permeable membrane barrier composed of a mixture of
polyvinyl chloride and polyaryl sulphone polymers. Preferred
proportions of the polymers are 1 to 9 parts of polyaryl sulphone for
each part of polyvinyl chloride, and the mixture may be formed into
membranes by solution casting. Preferably this barrier is used with an
inner membrane, especially of porous polycarbonate. In use, these
polymer mixtures are especially useful in their selective permeability
to glucose. Also provided are methods for their use in analysis, and
the polyvinyl chloride/polyaryl sulphone polymer compositions
themselves and membranes made from them.
