Abstract
A method and apparatus for monitoring low concentrations of certain ions present in a flowing fluid is described in which an isokinetic sample is passed through an electroseparative cell wherein, under the influence of an applied electrical field microgram quantities of the ionic species are quantitatively transferred through a microporous filter membrane. The membrane has a pore size related to cell efficiency.
