The AQUA 40.00 Vario combines the Karl Fischer Titration with the headspace technique. This offers a wide range of interesting applications to determine moisture in solid and pasty samples, oils and viscous compounds.The sample preparation takes place using the dynamic headspace technique. The sample - in a closed vial - is placed into the headspace oven and tempered.

High temperature oven HT 1300 is an extension module with high performance for the AQUA 40.00 for extracting the water from samples which release the water at higher temperatures.A special valve system transports the sample into the oven without interrupting the carrier gas circulation. An internal drying of the carrier gas in two steps realizes a low background drift.

Aquamax KF Plus titrators have been specifically designed for the determination of water content, combining coulometry with the Karl Fischer method.The versatile Aquamax KF Plus is suitable for a wide range of applications and offers many advantages including a tough measuring vessel, a ‘press go’ keypad and built-in printer.

Measuring and controlling the amount of water in oils is of considerable economic importance to the industrial community, particularly to the crude oil and electric power industries. Water content determination by Karl Fischer titration is no longer restricted to being used by a chemist in a laboratory – now the technique is used by engineers, plant operators, tanker drivers, distribution/maintenance engineers and other non-laboratory personnel.Karl Fischer titrations can now be performed in many different locations such as the tailgate of trucks, mobile laboratories, offshore installations, tankers, engineering workshops and dockside cabins.

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 device combines coulometric Karl Fischer method with an unique gas eva- poration and dosing procedure.

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 unique “closed loop” principle means no additional carrier gas is necessary. Directly injecting the sample in to the oven means no blank value is required, making the Aquamax KF PRO Oil a truly accurate, trace

The Titramax VT ALKALINITY is suitable for determination of carbonate and bicarbonate hardness of water samples. The alkalinity of natural waters is primary caused by hydroxyl ions in free state and the salts of carbonate and bicarbonate along with borates, silicates and phosphates.

The value of Bromine Index or Bromine Number expresses the trace amount of unsaturated constituents of hydrocarbons and oils. It is determined by measuring of consumed bromine for cleavage of double or multiple bounds during the titration. The value are needed for determination of parameters for further processing of petroleum products.

Determination of total acid or base number of oils and fats according to standards

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 (Ag S) and silver mercaptides. 2

The 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.

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.

Sulphide determination by gas extraction according to DIN 38405-27 No sample pre-treatment Also available as mobile compact version with low space requirement

The Sulfimax GX Go determines hydrogen sulphide and volatile sulphides in liquids and gases. The released H S gas is conducted to the 2 highly sensitive sensor, which detects H S 2 in the range of 0.01 to 10,000 ppm. If the Sulfimax GX Go is extended with the optionally available H S Headspace 2 Module, solid and pasty samples can also be measured. The sample can be dispensed directly by syringe without pretreatment.
