The QuadStat
This chapter describes how to connect and use your QuadStat.
The QuadStat (
EA164
) is a four-channel, three-electrode potentiostat
with gain ranges of 200 pA to 10 mA per channel). It can also be used
as a: bipotentiostat (two working electrodes with a common reference
and common auxiliary electrode), multiple working electrode
potentiostat (three or four working electrodes with a common reference
and auxiliary electrode); or as four-channel zero resistance ammeter
(ZRA).
It is ideal for monitoring multiple amperometric sensors such as those
used for: dissolved oxygen electrodes, nitric oxide electrodes, or
enzymatic biosensors. It can also be used for experimentation with
multiple small scale fuel cells (e.g. microbial fuel cells), small solar
panels, and mini-batteries or other small power sources.
Note that when used with EChem software only a single QuadStat
channel can be used. With Scope software one or two channels can be
used. With Chart software, one to four QuadStat channels can be
used.
IMPORTANT : This manual refers to QuadStat units, with serial numbers
of 164-113 and later). Earlier QuadStat units did not have a ZRA
operating mode, did not have all the gain range settings of the present
version, and had a 1 Mohm dummy cell (instead of the present
100 kohm dummy cell).
