The fixed ground-joint diaphragm allows low-noise potential measurements dependent only on the ionic strength and stirring speed, thus meeting crucial requirements for a rapid and precise titration
Metrohm says that the electrode, at the heart of every titration system, must meet high demands otherwise investment in a titrator will be in vain.
The continually increasing success of its Unitrode and Aquatrode Plus in pH measurement shows that the fixed ground joint is the more universal type of diaphragm.
It is largely insensitive to contaminants and requires only minimal maintenance.
The fixed ground-joint diaphragm is suitable for a wide range of samples, from clear, ion-deficient solutions up to highly concentrated suspensions or emulsions.
Its greatest strength, however, is its precision: the fixed ground-joint diaphragm allows low-noise potential measurements that are only dependent on the ionic strength and stirring speed to a minimal extent, thus meeting crucial requirements for a rapid and precise titration.
In order to utilise the advantages of the fixed ground-joint diaphragm to the full extent in titrations, a new type of membrane glass has also been developed for the Ecotrode Plus, which, in addition to a short response time, exhibits very high endurance.
In short: a membrane glass that does not give up easily, even in continuous use.
The 6.0262.100 Ecotrode Plus is the result of 60 years experience, ultramodern production technology and our continuous striving to optimise products.
In many ways this new Metrosensor represents a clear improvement of Metrohm's well-known workhorse 6.0232.100 Ecotrode.
With the Ecotrode Plus you document the changes in the sample and not the ageing of the electrode, says the company.
