1.1 Instrument description
The instrument 881 Compact IC pro – Anion is one of the model ver-
sions of the 881 Compact IC pro line of instruments manufactured by the
Metrohm Company. The 881 Compact IC pro line of instruments is distin-
guished by:
￭ the intelligence of its components, which are able to monitor and
optimize all functions and to provide documentation according to FDA
requirements.
￭ its compact style of construction.
￭ its transparency. All components are easily accessible and arranged in
a clear manner.
￭ its safety. Chemicals and electronics are separated and a leak sensor is
integrated in the wet end.
￭ its environmental compatibility.
￭ its low noise emission.
The instrument is operated with MagIC Net™ software. It is connected
via a USB connection to a PC on which MagIC Net™ is installed. The soft-
ware automatically recognizes the instrument and checks its functional
readiness. MagIC Net™ controls and monitors the instrument, evaluates
the measured data and administers it in a database. The operation of
MagIC Net™ is described in the online help or in the tutorial for
MagIC Net™.
The instrument contains the following components:
Eluent degasser
The eluent degasser removes gas bubbles and dissolved gases from the
eluent. For degassing, the eluent flows into a vacuum chamber through a
special fluoropolymer capillary.
High pressure pump
The intelligent and low pulsation high pressure pump pumps the eluent
through the system. It is equipped with a chip on which its technical spec-
ifications and "life history" (operating hours, service data, … ) are saved.
Inline filter
Inline filters protect the separation column securely against possible con-
tamination from the eluent. Inline filters can however also just as well be
used for the purpose of protecting other sensitive components against
contaminations in the solutions used. The filter platelets with a pore size
