Customised systems for robotic titration
Comprehensive systems include all the instrumentation, electrodes, and accessories that are required for the rapid, accurate and economical solution of the titration tasks
After the successful introduction of the Metrohm robotic sample processors, the company now presents the Mati systems, based on these novel sample changers which are tailored to the specific requirements of the titration laboratory These comprehensive systems include all the instrumentation, electrodes, and accessories that are required for the rapid, accurate and economical solution of the titration tasks

Mati-1 is a completely automated, PC controlled titration system for water analysis.
Based on the new 835 Titrando and the 815 robotic USB sample processor XL.
The latter performs the sample handling operations required.
It ions equipped with two 786 swing heads on which a titration head or the novel overflow burette is mounted.
Up to 59 water samples of 120ml each can be analysed in a single run.
At the first workstation the 712 Conductometer measures the conductivity and temperature, then the overflow burette transfers exactly 100ml of sample into the external titration cell in a matter of seconds.
Here the 835 Titrando measures first (carbonate hardness, alkalinity).
In both cases the Aquatrode Plus is used as the indicator electrode.
The final step of the complexometric titration of the calcium and magnesium hardness uses the Ca ion specific electrode.
When the determinations are finished the Titrando software outputs a comprehensive analysis report.
The spent sample solution is aspirated off completely and the propeller stirrer, electrodes, burette tips and titration vessels are thoroughly rinsed.
The corresponding analysis system for Metrohm Titrino titration users is the Mati-31.
It is based on the 799 GPT Titrino and the 789 robotic sample processor XL and also allows the conductivity, temperature, pH value, p and m values as well as the calcium and magnesium hardness to be determined fully automatically in 59 water samples.
Mati-31 is designed as a stand alone system, but can also be completely controlled from a PC via the TiNet software.
With the classical water analysis, Mati-1 and Mati-31 cover one of the most important applications in titration laboratories.
Additional Mati systems will follow, for example for the titration of the acid and base numbers in petrochemical products (TAN/TBN) or for the chemical oxygen demand (COD). Request a free brochure from Metrohm UK ...
