摘要
The invention relates to a closed system for automatically determining the quantity of cetyltrimethylammonium bromide is adsorbed by the carbon black in a dispersion of cetyltrimethylammonium bromide - carbon black. / p & & p & according to the invention, it comprises a container 2 containing the dispersion, a means for forcing the dispersion to leave the container, a filter adjusted in temperature 7 in communication with the container in order to form a filtrate of the dispersion, a measuring circuit 9 for measuring a specified quantity of the filtrate, a high pressure liquid chromatography column 10 separating cetyltrimethylammonium bromide, the remainder of the filtrate, a detector 13 of the presence of the separate cetyltrimethylammonium bromide, and an integrator 14 in order to determine the amount of cetyltrimethylammonium bromide, detected by the detector and this amount in relation to the quantity of cetyltrimethylammonium bromide is adsorbed by the carbon black. / p & & p & in particular, the invention applies to the measurement and to the analysis, in particular of carbon black.
