As simple as never before, this additive can also be analyzed using the 894 Professional CVS, thus making the comprehensive monitoring of the bath components complete. Save time and money with the 894 Professional CVS In order to reduce cost of ownership per determination, it is possible with the 894 Professional CVS to reduce the amount of the reagents used signifi cantly* in comparison with other systems. Furthermore, the duration of the analysis can also be reduced. This increases sample throughput and helps keeping cost of ownership low. * Up to 70% of the quantity usually used The 894 Professional CVS in detail 06 Even the manual version of the 894 Professional CVS is a Last but not least, the 894 Professional CVS is a class of its fully­fledged CVS analysis system when combined with a own due to its attractive design. separately available electrode kit for the respective application. The system’s internal calibrator and the new potentiostat that is extremely accurate in all measuring ranges provide for superior accuracy and sensitivity of measurements. Quick method change due to exchangable 07 measuring head Thanks to the new, exchangable measuring head, the measuring system can be refitted for a different application in just a matter of seconds. Three short steps are all it takes to replace all of the electrodes and tubing connections. Superior reliability of measurements due to integrated calibrator The 894 Professional CVS has a built­in certified calibrator. This is used to readjust the potentiostat prior to each measurement. Even in the case of changing ambient conditions (temperature, humidity, etc.), this ensures that the measurement is always accurate and reliable. High performance on a small footprint With a footprint of only 18.8 cm × 45.2 cm, the 894 Professional CVS takes up only very little bench space. The modular design makes it convenient to use and allows maximum flexibility as desired and required. Communication power 4 MSB connections permit the operation of several 800 Dosinos. The 894 Professional CVS is connected to the computer via USB. An integrated USB hub enables the connection of additional PC peripheral devices, e.g. printers or barcode readers. Temperature measurement The optional temperature sensor does not only record the temperature of measuring solution. Together with a temperature controlled water bath it is possible to control the temperature of the measuring solution for even more reliable measuring results. Metrohm CVS systems – flexible automation 08 Flexible and modular MVA-21 894 Professional CVS automated Thanks to the modular concept, a manually operated 894 Fully automated system is recommended wherever a Professional CVS is quickly upgraded to a fully automatic particularly high sample throughput is required.

In addition to available calibration techniques are of course supported that, for the first time, a combination of different calibrawithout any additional limitations. tion techniques is possible without limitation. 894 Professional CVS semiautomated Routine analysis is made significantly easier with the semiautomated system. The 894 Professional CVS semiautomated is recommended for routine analysis of organic additives in individual plating bath samples. It enables the convenient performance of determinations with a minimum intervention by laboratory personnel. VMS and the sample are automatically added with 800 Dosino dosing systems. An optional accessory kit is available for semiautomated brightener determinations. This enables the automatic addition of intercept solution and brightener standard solution. Only the sample needs to be added manually. The measuring vessel can be rinsed automatically after each analysis by an optionally available 843 Pump Station. This enhances both user convenience and measuring accuracy, as the need for user intervention is reduced to a minimum. MVA-20 894 Professional CVS automated The MVA­20 894 Professional CVS automated is a fully automated system with sample changer intended for CVS analysis in any routine laboratory for a small to medium­sized number of samples. With the MVA­20, the samples are automatically introduced by a 919 IC Auto­ sampler plus for CVS. On this system the suppressor content can be determined in a series of up to 27 samples. Up to 14 samples can be analyzed automatically during brightener determination series. The possibility of recalibrating methods during a sample series provides for highest accuracy. It is also possible to combine various calibration techniques in a determination series.

Easy to use and highly fl exible, viva is the fi rst CVS software in the market allowing individual, taskfocused method programming. The user­friendliness of the software is clearly visible in the «Workplace» of the user interface. All of the information re quired for the determination is presented here. It goes without saying that the layout of «Workplace» can be confi gured at discretion so that only data relevant to the user is displayed.

With just a few Animated graphics and text information in the live window provide the user with an overview of the progress of the current measurement. The display of the measured voltammogram in real time, information on the remaining measurement time or on the status of the pumps or 800 Dosinos being used are all information that is available at any time while a method is running and that provide information on the current measurement. The method used and the associated evaluation parameters are clearly displayed in the method window. The current command is highlighted in color during a measurement.

The determinations can be viewed in the «Database» program part, along with all of the determination, method, and instrument parameters. The determination overview can be freely confi gured. This means that all measurement results can be easily viewed. In the «Curve» and «Information» subwindows, the respective measurement curve, calibration curve, and other information on the determination, method, and instrument parameters can be viewed for the selected determination.
