Determination of trace water in petrochemicals

The 831 KF Coulometer masters a number of analytical tasks.

It determines even ultratraces of water with great accuracy.

Other features are its compact design, flexibility, and easy operation.

The 831 KF Coulometer is suited to routine operations.

An expert mode and standard mode are available.

The expert mode allows the use of all the features of the device.

In the standard mode, only functions needed in routine work are accessible; operation in this mode is simple and requires few keystrokes.

Connecting 700 Dosino to the 831 KF Coulometer allows you to siphon off the contents of the coulometric cell and fill it with fresh reagent.

As the KF vessel remains closed, no humidity can enter the system.

Within a minimum of time, the analysis cell is again conditioned.

Use of a KF Oven is recommended for samples that cannot be introduced directly into the KF cell.

The 832 KF Oven can be used if only a few samples need to be processed.

However, the 774 Oven Sample Processor is the answer for analysis of a large number of samples.

When combined with the 831 KF Coulometer, the sample changer allows fully automated water determination in up to 35 samples.

The analysis system can be operated as a standalone unit, or it can be controlled by Metrohm titration software.

The 831 KF Coulometer allows the clear documentation of all determinations performed.

The result output complies with GLP and includes the designation and the serial number of the instrument, software version, date, user name, and method used.

GLP and ISO 9000 functions, such as service or validation intervals, alert you in time for the necessary tests.
