| The electrode used for the titration is really
the most important component of any titration system,
and until now it has been just this electrode that has
formed the last gap in traceability. The 857
Titrando with iConnect now closes this gap and therefore
guarantees complete traceability of the analytical result
to each component participating in the analysis.
iConnect and iTrode prevent
- the use of an incorrect electrode,
- the use of an electrode whose calibration period
or working life has expired.
The 854 iConnect is electrode cable
and measuring amplifier in one. The iTrodes of the new
intelligent electrode generation confirm Metrohm’s
leadership in the field of potentiometric titration.
The built-in memory chip allows the
storage of such important sensor data
as article and serial numbers, calibration data, calibration
history, working life and calibration validity period.
All the sensor data are read in automatically
when the iTrode is connected to the 857 Titrando. Mix-ups
or editing errors are therefore eliminated.
The electrode is identified automatically. If the
type of electrode is not the same as that defined in
the method then the user is informed. This means that
it is not possible to use an incorrect electrode.
Monitoring functions allow the exclusion
of electrodes whose calibration data lie outside the
limits or whose calibration period has already expired.
If the sensor is used with different instruments or
if you wish to prevent inexperienced users from having
to calibrate the electrode on their own instruments
then the electrode can be calibrated on a different
instrument under defined conditions. The calibration
data stored in the chip make the electrode
transferable; it does not need to be recalibrated each
time that it is used with a different instrument.
Compatible with all existing sensors
Despite its new digital measuring interface and intelligent
sensors, the 857
Titrando with combined analog and digital measuring
amplifier (2.857.0020) also supports conventional sensors.
This means that you can continue to use all your sensors. |
