Determination of hydrogen sulphide and mercaptan sulphur in hydrocarbons and oils

The Titramax VT SULPHUR is designed for the determination of sulphur compounds as hydrogen sulphide and mercaptan sulphur in liquid hydrocarbons and oils.

The measurement uses a volumetric titration method with silver nitrate solution in an anhydrous medium. This measurement generates silver sulphide (Ag2S) and silver mercaptides.

The device is conform to standards ASTM D 3227, ISO 3012, UOP 163, UOP 212.

The analysis must be done in an inert gas atmosphere to avoid an oxidation of sulphur compounds by air and thus false measurement results.

The titration speed is precisely adjusted to the reaction rate with control algorithms. Two end points get indicated – first for hydrogen sulphide and second for mercaptan sulphur.

At the end of the measurement, results are shown in mg/kg (ppm) hydrogen sulphide and/or mercaptan sulphur or several other units.


The Titramax VT SULPHUR is suitable for analysis of

  • fuels (gasoline, kerosines, aviation turbine fuels)
  • volatile distillates, middle distillates
  • liquified petroleum gas (LPG)
  • hydrocarbon gases
  • liquid hydrocarbons
  • naphtha (petroleum)
  • low boiling oils
  • light cycle oils
  • heavy cycle oils


  • Complete measuring system for the determination of hydrogen sulphide and mercaptan sulphur
  • Fully-automatic volumetric titration
  • Precise control of the titration parameters by special control algorithms
  • Preset measurement method allows an immediate start
  • The result output can be adjusted to your needs by using a formula generator
