| description | 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).
L'invention porte sur des procédés et un appareil (50) qui permettent de mesurer avec précision de faibles concentrations de bore dans l'eau déionisée sous l'effet de la réaction chimique de l'acide borique avec un polyol en injectant de très petites quantités de polyol concentré dans des courants d'échantillons d'eau avec et sans bore afin d'obtenir un produit acide ionisé, et en mesurant ensuite la différence de conductivité (conductivité delta), corrigée pour des facteurs d'interférence ou exogènes qui peuvent affecter la conductivité entre ces échantillons avec bore et sans bore, au moyen d'un détecteur (23) de conductivité et de température. |
