1.1 Instrument description
The IC Amperometric Detector is an intelligent amperometric detector
that is used in the detector chamber of the instruments of the 850 Profes-
sional IC, the 881 Compact IC pro and the 882 Compact IC plus line of
instruments.
With the IC Amperometric Detector, electroactive substances can be
determined in the mobile phase of an IC system. Amperometric methods
are used for the determination which combine an outstanding sensitivity
with a high degree of selectivity.
The installed potentiostat generates the voltages for the direct current
amperometry (DC), for the pulse amperometry (PAD) and the flexible inte-
grated pulse amperometry (flexIPAD) as well as for the recording of cyclo-
voltammograms.
The installed preheating capillary ensures a constant eluent temperature
on the cell.
On the one hand, the built-in leak sensor detects fluid that has escaped in
the interior of the detector, while on the other it also responds when too
much fluid has backed up in the tray on the front side of the detector. As
a result of this, the leaking instrument is shut down and the ongoing
determinations are canceled.
The IC Amperometric Detector can only be used together with the IC
instrument. It is utilized in the detector chamber of the IC instrument.
The IC system is operated with MagIC Net™ software. When the IC
instrument is switched on, MagIC Net™ recognizes the IC Amperometric
Detector automatically and checks its functional readiness. MagIC Net™
controls and monitors all of the instruments combined to form an IC sys-
tem, evaluates the measured data and manages it in a database.
Additional information for the operation of MagIC Net™ can be found in
the online help and in the tutorial for MagIC Net™.
