Automation in titration
Introduction to automation
The automation of potentiometric measuring methods
has gained enormously in importance as these
days single determinations are hardly ever sufficient. In
contrast to a manual determination, a fully automatic
determination is more precise, reliable and saves time.
Facing large numbers of samples, users are soon
forced to think about automating frequent and identical
analyses, as this allows qualified personnel to be
used more efficiently. Even with small series or many
different analyses, automation can be used to achieve
faster and more reproducible results.
A uniform sample preparation procedure, which
can only be guaranteed by a fully automated system,
ensures that results remain identical even over a longer
period of time – regardless of the user. Typical preparation
steps in daily laboratory routine such as liquid
handling (pipetting, transferring), diluting, adding, thermostatting,
degassing, milling, filtering, filling off and
many more can also be carried out fully automatically
just like the subsequent analytical determination.
An issue not to be neglected is the safety of the
laboratory workers. The routine handling of typical
laboratory equipment (pipets, burets, etc.) and the use
of aggressive chemicals requires the technician's full
concentration. The use of automated systems with
sample preparation minimizes contact with hazardous
substances and solvents and in this way makes an
enormous contribution to safety at work.
Metrohm offers a large selection of instruments for
automating your analytical and sample preparation
procedures. On the following pages you will find more
information about different sample changers and fully
preconfigured analysis systems.
