Aqua 40.00 Karl Ficsher Titrator

The basic module is the essential device for microcoulometric water determination according to Karl-Fischer-Titration in liquid samples and gases. This coulometric titration is based on the electrochemical generation of the iodine needed for the determination. There is no need for any working with titrator of KF-reagent and its adjustment.
The optimized measuring cell allows very low background drift and short preconditioning times. Therefore the coulometric method can be used as a known to trace ppm-analysis.
The sample to be analyzed is injected right into the measuring cell.
The titration current is adjusted automatically and continuously to the amount of water. Short measuring times are realized.
Measuring cells without diaphragm can be used. Many applications do not require a diaphragm, so only one coulometric reagent is needed. All customary KF-reagents are suitable.
The basic module can be upgraded with additional modules available on request.

Applications

Water determination according to Karl-Fischer-Titration in
• Solvents
• Lyophilisates
• Petro-chemicals
• Biodiesel
• Hydraulic oils / Mineral oils
• Solids via liquid extraction

Extension Modules

Headspace module:

• universal module for all kind of samples: solids, pasty substances and oils
• designed for samples that change the water content if in contact with ambient air
• heating procedure with freely definable temperature or temperature programs
• analysis of closed sample vials for hygroscopic samples

Heating module for oils and for solids:

• Gas extraction – the ideal method to handle oils, solid and pasty substances
• heating procedure with freely definable temperature or temperature programs
• with closed-loop gas circulation, the drying of carrier gas is no longer necessary
• heating module of oils is used for oil volumes up to 20 ml
• heating module of solids is used for very small sample amounts (below 10 μg)

High temperature oven module:

• this oven can heat out the sample at temperatures ranging up to 1300 °C.
• a special valve system transports the sample into the oven without interrupting the carrier gas circulation.
• Internal drying of carrier gas

Gas sampling module:

• The gas-sampling module is mounted on the basic module and can be used for determination of water down to 1 ppm, e.g. in natural gas, industrial gas, biogas and pressurized gas
• allows precise and reproducible dosing of gas volumes into the measuring cell directly
• portable version or gas sampling module for laboratory

Advantages

• Infinitely variable electrolysis current for very fast analysis
• Adjustment of titration rate to current amount of water to be titrated
• Low background drift
• All customary KF-reagents are suitable
• Easy-to-use software
• Defined methods for measurement
• Status display through large-scale colouration
• Addional heating modules can be used
