Water determination according to standards of ASTM, API, BS, DIN, EI/IP, EN, IEC, ISO, Ph. Eur.

Aquamax KF Plus titrators have been specifically designed for the determination of water content, combining coulometry with the Karl Fischer method. 

The Aquamax KF PRO LPG fulfils the requirements of the standard ASTM D 7995 – 19: Standard Test Method for Total Water in Liquid Butane by Liquefied Gas Sampler and Coulometric Karl Fischer Titration.

The Aquamax KF PRO LPG is designed for an easy and accurate determination of water in liquefied and gaseous samples such as LPG and LNG. 

The Aquamax KF PRO Oil fulfils the requirements of the standard ASTM D 6304: Standard Test Method for Determination of Water in Petroleum Products, Lubricating Oils and Additives by Coulometric Karl Fischer Titration.

The Aquamax KF PRO Oil is the perfect instrument to measure ppm water in oils and fuels without the worry of interference side reactions caused by additives or sulphur/mercaptans. 

The gas extraction is the ideal method to detect moisture in oil samples and viscous substances. The Aquamax KF Online is suitable for continuous analysis of water in oil samples.

Trace amounts of water can be measured with the special heating chamber for oils. The sample has no contact with the reagent. Therefore the consumption of reagent is low and the detection sensitivity is high.

The AQUA 40.00 (Basic Module) determines the water content of liquid samples and gases quickly and precisely. Based on coulometric Karl Fischer titration, the instrument requires little space due to its compact design.

The sample is simply dispensed through a septum directly into the measuring cell. The cell is optimally designed and exhibits extremely low background drift. The titrator is thus particularly suitable for water determination in the trace range.

The High temperature oven HT 1300 is an extension module with high performance for the Karl Fischer titrator AQUA 40.00 for extracting the water from samples which release the water at higher temperatures (300 to 1300 °C). 

Samples are put into small sample boats into the hot area of the oven. A special valve system transports the sample into the oven without interrupting the carrier gas flow.

The Titramax VT ACID/BASE is suitable for determination of acids and bases, buffer capacities, carbonates, bicarbonates and other ions in water samples.

Among other things, the titrator fulfils the requirements of the standards ASTM D 1067, ASTM D 1121, DIN 38409-7, DIN EN ISO 787-4, DIN ISO 125, ISO 10539.

The value of Bromine Index or Bromine Number expresses the trace amount of unsaturated constituents of hydrocarbons and oils. Determined by measurment of consumed bromine for cleavage of double or multiple bounds during the titration. The values are needed to determine parameters for further processing of petroleum products.

The Titramax VT BROMINE is conform to standards ASTM D 1159, ASTM D 2710 and ASTM D 5776.

The Titramax VT CHLORIDE can be used to determine the chloride concentration in water samples and water-soluble components from solids and organic mixtures. The method is suitable for contents from 0.001 % to 100 %. In foodstuffs the contents are very high, in natural waters or petroleum very low.

The titrator meets ASTM C 1218, D 4458-15, D 4929-22, D 6470-99; DIN EN 196-2; ISO 5810, 5943, 6227, 9197-1; UOP 456-80 requirements.

The TAN/TBN Titrator 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 instrument conforms to standards ASTM D 664, DIN 51558, IEC 62021-1, Pharmacopoeia (TAN) and ASTM D 2896, ASTM D 4739, ISO 3771, UOP 269 (TBN).

With the Titramax VT WATER you can determine the water content of liquids very easily. The device is based on volumetric titration according to the Karl Fischer method. The titrator works fast and precise for a wide range of use.

The device is conform to standards ASTM D 4377, ASTM D 6869, ASTM E 203, DIN 51777, IP 356, IP 471, ISO 10336, ISO 6296, Pharmacopoeia.

The Sulfimax GX Lab provides precise, standard-compliant determination of hydrogen sulphide (H₂S) and volatile sulphides in liquids and gases, without the need for sample pre-treatment. Samples are introduced manually or via autosampler, and efficient gas extraction ensures complete H₂S release with minimal interference. The sensitive sensor detects concentrations from 0.01 to 10,000 ppm within approximately five minutes. With the optional Headspace Module, solid and pasty samples can also be analysed.

The Sulfimax GX Go is a compact, portable version of the Sulfimax GX series, ideal for on-site measurement of hydrogen sulphide (H₂S) and volatile sulphides in liquids and gases. Samples are introduced directly by syringe without pre-treatment, and efficient gas extraction ensures complete H₂S release. With detection from 0.01 to 10,000 ppm in about five minutes, the optional Headspace Module also enables analysis of solid and pasty samples.

The Headspace Module extends the Sulfimax GX system for easy determination of volatile hydrogen sulphide (H₂S) in solid and pasty samples. Samples are placed in glass vials and heated between 30 °C and 180 °C, releasing H₂S into the gas circuit for precise detection. No sample preparation is required, and fast measurement times enable high throughput in a compact, user-friendly design.
