ABSTRACT:
An electrode assembly comprising an organic plastic sample flow-through tube, a portion of the wall of which comprises a membrane, the membrane comprising a matrix of an organic plastic material containing a non-volatile solvent-plasticizer and an ion exchange material dissolved in the solvent plasticizer, the membrane chemically bonded to and integral with said tube. The method of forming the membrane to the tube comprises dissolving the matrix material, the ion exchange material and the non-volatile plasticizer in a volatile solvent, placing the resulting solution on a surface and evaporating the volatile solvent to form the membrane, contacting an edge of the tube to the membrane material, contacting the tube edge with said volatile solvent and allowing the solvent to evaporate.
