Methods and apparatus (50) 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 (23).
