the diagnostic tool for potentiometric and test to be certain metrohm instruments are known for their precision and reliability thanks to their robust construction they are hardly ever affected by external mechanical or electrical influences even though a malfunction can never be completely excluded it is normally due to operator errors faulty connections or third-party instruments should you ever suspect a fault in a metrohm instrument it is always advisable to localize the problem using fast and easy to perform diagnostic tests these diagnostic tests require tools that are not readily found in the laboratory the 822 titration curve simulator is such a tool it is connected instead of the electrode is extremely easy to operate and allows to generate potentiometric as well as karl fischer titration curves by means of these curves you can rapidly gauge the proper functioning and the accuracy of the instrument concerned 822 titration curve simulator with 808 titrando and titration curve

karl fischer titrators how does it work as a function of the dispensed volume the 822 titration curve simulator generates a voltage that changes with each dosing step the resulting sshaped curve can have one or more equivalence points and is suitable for all current metrohm titration systems the titration curve data are digitally stored in the curve simulator this allows one to obtain strictly reproducible equivalence points delicate evaluation occasionally it may happen that previously found equivalence points suddenly are no longer evaluated is it the chemistry the solvent the electrodes or even the titrator or has there been a sudden change in the sample these are the questions that confront the analyst the titration curve simulator also generates extremely flat curves that nevertheless can be evaluated if your titrator is able to evaluate such curves an instrument fault can be excluded this means that the range of possible error sources is reduced quickly and economically practic
