Titramax VT TAN/TBN

Product description

The TAN/TBN Titrator Titramax VT TAN/TBN is suitable for determination of Total Acid Number (TAN) or Total Base Number (TBN) of oils and fats. The acid number expresses the quantity of base required to neutralize all acidic constituents of the sample. It is a quality feature for freshness of oils and fats. The base number indicates the quantity of acid which can be neutralized by additives in mineral oils.

The device is conform to standards ASTM D 664, DIN 51558, IEC 62021-1, Pharmacopoeia (TAN) and ASTM D 2896, ASTM D 4739, ISO 3771, UOP 269 (TBN).

The measurement uses a potentiometric titration method in an anhydrous medium. The titration with titrant starts, once the oil sample is dosed into the reagent. The user has to enter the sample weight into the menu. The titration speed is precisely adjusted to the reaction rate by control algorithms.

The titration is performed automatically until the endpoint indication of measurement. At the end of the measurement, results are shown in mg KOH/g oil or several other units.

Features

The Titramax VT TAN/TBN consists of

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

The determination of TAN/TBN value is based on

• an acid-base-titration in an anhydrous medium,
• a precise indication by an electrode filled with anhydrous ethanol/LiCl.

Steps of the analysis

1. Calibration of the electrode
2. Determination of the blank value
3. Standardization of the titration solution
4. Titration of oil samples
