Titratmax VT SULPHUR

Product description

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.

Features

The Titramax VT SULPHUR consists of

• an automatic volumetric titrator with potentiometric indication,
• a titration vessel with stirrer unit.

The determination of hydrogen sulphide/mercaptan sulphur is based on

• a potentiometric titration with silver nitrate solution in an anhydrous medium,
• a precise indication by a selective silver electrode, which is stable over long periods.

Steps of the analysis

1. Standardization of the titration solution
2. Titration of oil sample or absorption liquid
