HK-DP-LC200 Mercaptan Sulfur Content (Potentiometric Titration Method)

Mercaptan sulfur has an objectionable odor, an adverse effect on fuel system elastomers, and is corrosive to fuel system components.


The Instrument adopts potentiometric titration method: The hydrogen sulfide-free sample is dissolved in an alcoholic sodium acetate titration solvent and titrated potentiometrically with silver nitrate solution, using as an indicator the potential between a glass reference electrode and a silver/silver-sulfide indicating electrode. Under these conditions, the mercaptan sulfur is precipitated as silver mercaptide and the end point of the titration is shown by a large change in cell potential.

Suitable scope

The instrument is used for determination of mercaptan sulfur in gasolines, kerosines, aviation turbine fuels, and distillate fuels containing from 0.0003 to 0.01 mass % of mercaptan sulfur. Organic sulfur compounds such as sulfides, disulfides, and thiophene, do not interfere. Elemental sulfur in amounts less than 0.0005 mass % does not interfere. Hydrogen sulfide will interfere if not removed


1.Windows operating platform with convenient operation, straightforward dialog between operator and machine.

2.Real-time display of the titration curve can print and store the titration curve, testing results and data directly.

3.We adopt imported titration unit, makes the instrument measuring accuracy is higher and better stability.

4.The instrument can do the following functions automatically.

5.Cleaning, setting value add fluid, detect end point, filtering false end. And it features Continuous Titration function
