L'acide borique reagit avec l'acide chromotropique pour former un complexe anionique, detecte par fluorimetrie, apres separation par HPLC. La formation du compose acide borique/acide chromotropique est favorisee par la presence de sels d'ammonium quaternaire. Les teneurs en bore dosees sont inferieures au ppb
