1 Introduction
1.1 Description
The Wall-Jet cell is used for amperometric detection with the Amperomet-
ric Detector. The Wall-Jet cell applies the wall-jet principle, which means
that the inlet is positioned directly opposite the working electrode. A thin
vertical jet of eluate is directed onto the working electrode, thus enabling
an optimum measurement performance.
The IC equipment Wall-Jet cell is available in four versions:
￭ Wall-Jet cell without electrodes (6.5337.000).
￭ Wall-Jet cell Carb (6.5337.010), with one gold working electrode and
one palladium reference electrode for the analysis of sugars and amino
acids.
￭ Wall-Jet cell Cyanide (6.5337.020), with one silver working electrode
and one palladium reference electrode for applications relating to envi-
ronmental analysis, e.g. the determination of cyanide and sulfide.
￭ Wall-Jet cell Anion (6.5331.030), with one glassy carbon working elec-
trode and one silver / silver chloride reference electrode for the analysis
of inorganic anions, e.g. nitrite, sulfite and iodide.
A more detailed description of the specifications and areas of application
for the individual cells can be found in Chapter 6, page 20.
1.2 About the documentation
