Abstract
Methods and apparatus () are disclosed for accurately measuring low concentrations of boron in deionized water utilizing the chemical reaction of boric acid with a polyol by injecting very small plugs of concentrated polyol into streams of boron containing and non-boron containing water samples to produce an ionized acids product, and then measuring the conductivity difference (delta conductivity), corrected for interfering or extraneous factors which can effect conductivity, between such boron containing and non-boron containing samples using a conductivity and temperature detector ().
