This method is for determining basic organic nitrogen in clearor very light-colored distillates using a visual indicatortitration. It is applicable over the range 0.1 to 100 mass-ppm asnitrogen, but is especially useful from 0.1 to 1.0 ppm. Coloredsamples interfere with the observation of the color indicator and,therefore, cannot be accurately analyzed by this method. Coloredsamples can be analyzed over a wide concentration range by UOPMethod 269.
