• Hydrogen Sulfide and Mercaptan Sulfur Titrator

Hydrogen Sulfide and Mercaptan Sulfur Titrator



For rating the tendencies of gas turbine fuels to deposit decomposition products within the fuel system. Measures the high temperature stability of gas turbine fuels using an instrument that subjects the test fuel to conditions that can be related to those occurring in gas turbine engine fuel systems. The fuel is pumped at a fixed volumetric flow rate through a heater, after which it enters a precision stainless steel filter where fuel degradation products may become trapped.

  • Conforms to the Specifications of ASTM D3227; ISO 3012; UOP 163, UOP 212
  • Complete measuring system for the determination of hydrogen sulfide and mercaptan sulfur
  • 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

The Sulfur Titrator is designed for the determination of sulfur compounds as hydrogen sulfide and mercaptan sulfur in liquid hydrocarbons and oils. The measurement uses a volumetric titration method with silver nitrate solution in an anhydrous medium. This measurement generates silver sulfide (Ag2S) and silver mercaptides.

The analysis must be done in an inert gas atmosphere to avoid an oxidation of sulfur compounds by air and thus false measurement results. The device conforms to standards ISO 3012, ASTM D3227, UOP 163, UOP 212.

The titration speed is precisely adjusted to the reaction rate with control algorithms. Two end points get indicated – first for hydrogen sulfide and second for mercaptan sulfur. At the end of the measurement, results are shown in mg/kg (ppm) hydrogen sulfide and/or mercaptan sulfur or several other units.
