Reference electrode assembly

摘要

Inter alia, a reference electrode assembly having a constrained-diffusion liquid junction between a liquid junction solution and a sample solution having separate flow paths, characterised in that it comprises: (a) a flow cell having attached thereto a constraint comprising a region of porous material permeable to water and salts; (b) a remote reservoir for holding the said liquid junction solution; (c) a means for moving the said liquid junction solution from the said reservoir to the said constraint; and (d) a reference contact region; is disclosed.
