Manual
The Manual tab of the 817 Bioscan window is only available
for a connected system.
Mode Selection of detector mode:
DC In the DC mode a constant potential is ap-
plied; the analytes are oxidized or reduced
in accordance with their electrochemical
properties.
Pulse The Pulse mode works with three different
potentials that are applied cyclically. This
frees the electrode surface from any adher-
ing reaction products during each sweep
and an activated surface is produced for
the next measurement.
Scan The Scan mode allows potential/current
curves to be recorded.
