The Mütek PCD-04 measures colloidally dissolved substances in a process sample.  It is a standard tool for detecting anionic trash levels as well as for checking chemical additives.  The Mütek PCD-04 Travel is equipped with an optional pH probe, the pH value of samples can be monitored.

The PCD-04 Travel is a true stand-alone lab instruments and perfectly suited for the frequent traveller and the newcomer to charge measurement, offering a built-in titration module.  Cartridges with standard poly-electrolyte solutions and a special titration algorithm make titrations easy and guarantee reproducible results.  Each cartridge is automatically recognised by the module, and its condition - titrant type, normality, factor and volume - is shown on the touch panel.

Titration results can be stored on a memory card or transferred via a USB port to your computer.  By using the tailor-made software Mütek ChargeView you can establish your own charge measurement database to compare them also with results obtained by the Mütek SZP-10.

Measuring Principle

The aqueous sample is placed in the measuring cell.  Once the PCD is turned on, the piston of the cell oscillates and causes a high flow rate.  Any charged material adsorbed to the cell wall will be separated from its counter-ions by the flow to create a streaming current.  Two electrodes in the cell pick up this current and display it on the touchscreen.  The titration module will automatically select the titrant which is charged oppositely to the sample (anionic sample - cationic titrant) and add it to the sample until 0 mV is reached.  As a result the consumption of titrant in ml is indicated on the display as well as the charge demand in µeq/l.
