Modular gradient system with 871 Bioscan for sugar analysis
As a stand-alone analyzer or as a component of a modular
IC system, the Bioscan analyzes:
- Carbohydrates
- Alcohols
- Sugar alcohols
- Oxidizable substances
The
Bioscan extends Metrohm's modular ion chromatography
system. With this instrument, carbohydrate analysis
is now included in the range of IC applications. The
heart of the Bioscan is a pulsed amperometric detector
that is located in an insulated column oven. Control
and data acquisition are carried out automatically via
the Metrodata IC
Net 2.1 or higher software.
Thanks to the modularity of the Metrohm IC system,
the individual components can be combined at will. This
means that it is possible to operate a stand-alone system
with the Bioscan pulsed amperometric detector or the
detector can be integrated into an existing standard
IC system for the determination of anions and cations.
The stand-alone system only requires the additional
use of a 818
IC Pump and an 812
Valve Unit. The Valve Unit is available in two versions,
with either one or two metal-free injectors. It can
be used for any applications that require additional
valves.
Additional to the stand-alone system with the Bioscan
it is possible to add a second 818 IC Pump. The advanced
set up allows to work with gradient eluent system. The
high pressure gradient is mixed in the gradient mixing
spiral. The controlling of the eluent composition can
be done by the software IC
Net 2.1 or higher (manual or time program).
The measuring cell of the Bioscan is integrated into
the insulated column oven and is thus optimally protected
against interferences. The three-electrode technique
is applied, the standard working electrode is the gold
electrode. Depending on the application, the detector
can be operated in the DC mode, Scan mode or Pulse mode.
The latter is used for determining carbohydrates, three
different working potentials being applied in a cyclic
fashion.
