Analysis and measurement of water content of meat

Meat contains a relatively large amount of water that is enclosed in cells.

Meat contains a relatively large amount of water that is enclosed in cells.

The water content of raw beef (whole brisket) for example is about 70% but also pork or sausages can be analysed.

Therefore, the volumetric method of the water determination by Karl Fischer titration is appropriate.

the necessary devices for carrying out the analysis are listed below.

A Polytron (high-frequency mixer) is used for extracting the water from the cells.

The Karl Fischer water determination is one of the most frequently applied laboratory methods.

In contrast to other water determination methods it is specific as well as rapid and requires no expensive equipment.

With an application range of 0.1% to 100% water the volumetric Karl Fischer titration is used in a wide variety of fields.

No matter whether you determine the water content in food, cosmetics or pharmaceutical products, the 841 Titrando is always the right instrument.

The sophisticated control algorithm of the Titrando has been adapted to the characteristics of the Karl Fischer reaction and guarantees highly precise results.

You can choose between a polarised alternating current (Ipol) or a defined voltage (Upol) to be applied to the electrode.

Both working modes yield fast and precise results.

Different reagents require different parameters.

The 841 Titrando lets you select the appropriate method for each type of reagent.

Combined with the easy and intuitive user guidance this is the optimal instrument for routine operation as well as for demanding applications in research labs.

With the 841 Titrando you acquire a titration system that meets all imaginable requirements and demands no compromises.

Just one example: The KF icons show you at a glance whether the instrument is still busy conditioning or whether you can start the water determination.

The electrode test and the newly created parameter

If, for example, the electrode is not connected correctly or the titration cell is very humid, conditioning is stopped after a given time or a given volume of KF reagent added.

This new feature increases work safety in the laboratory.
