MicroC,
WPI's low cost and elegant instrument for electrochemical
detection using carbon microelectrodes, will record the
presence and concentration of oxidizable biological
compounds in vivo and in vitro. Featuring inherently low
noise and a sensitivity of 1 millivolt per picoampere of
oxidation current. Response time to quantal catecholamine
release is less than 1 millisecond. When used with carbon
micro disk or carbon fibre microelectrodes, redox current
can be recorded over a range of 1 picoampere to 2
microamperes. The built-in carbon electrode activation
feature allows the easy renewal of electrode sensitivity.
In addition, MicroC features a low-pass filter and the
option of applying DC potential externally. A wide range
of compounds can be detected: dopamine, epinephrine,
norepinephrine, serotonin, ascorbic acid, etc. Other
compounds, such as glutamate, glucose, acetylcholine and
alcohol, can also be detected with MicroC using
enzyme-modified biosensors.
At
user's request, the applied potential range (currently 0
to 1.2 V) can be extended to (-1.2 to 1.2 V) or (-2.5 to
2.5 V). Please quote X844 when ordering. The MicroC
Potentiostat is supplied with a carbon electrode probe,
with 5 feet triax cable, which accepts 0.79 mm connector
pin, and a reference electrode with a 4 mm Ag/AgCl half
cell (see page 12). For applications where smaller half
cells are needed, please call WPI for more information.

Microelectrodes
Micro C can be used successfully with your own
microelectrode or one of WPI's microdisc (10 microns)
or carbon fibre (8 or 30 microns) microelectrodes (see
below).
