884 Professional VA semiautomated for CVS

884 Professional VA semiautomated for CVS
Beställningsnummer: 2.884.1210

884 Professional VA semi-automated for CVS is a convenient high-end routine analyzer for determinations of organic additives in electroplating baths with "Cyclic Voltammetric Stripping" (CVS), "Cyclic Pulse Voltammetric Stripping" (CPVS), and chronopotentiometry (CP), or voltammetric heavy metal determinations with rotating disk electrodes. The proven Metrohm electrode method combined with a completely new design of potentiostat/galvanostat and the extremely high-performance viva software opens up new perspectives in CVS. The potentiostat with a certified calibrator readjusts itself automatically before each measurement, thus guaranteeing maximum precision. The integrated temperature measurement input allows you to monitor the solution temperature during the measurement.

The instrument can also be used to perform voltammetric determinations with the Multi-Mode Electrode or the scTRACE Gold. The replaceable measuring head enables rapid changes between various applications with different electrodes.

Two 800 Dosinos (supplied) permit the automatic addition of auxiliary solutions during the determination, e.g., VMS, standard solutions or samples for the Dilution Titration technique (DT).

The viva software is required for control, data acquisition, and evaluation.

The 884 Professional VA semiautomated for CVS is supplied with extensive accessories and measuring head for rotating disk electrodes. Electrode set and viva license need to be ordered separately.
