At the end of the measurement, results are shown in mg Br /100 g 2 (Bromine Index) or g Br /100 g (Bromine Number). 2 The value of Bromine Index or Bromine Number expresses the trace amount of unsaturated constituents of hydrocarbons and oils. It is determined by measuring of consumed bromine for cleavage of double or multiple bounds during the titration. The value are needed for determination of parameters for further processing of petroleum products. The Titramax VT BROMINE is conform to standards ASTM D 1159, ASTM D 2710 and ASTM D 5776. The measurement uses a potentiometric titration method in an anhydrous medium. The titration with titrant starts, once the sample is dosed into the reagent. The user has to enter the sample weight into the menu. The titration is performed automatically until the endpoint indication of measurement.
