1. Introduction
1.1 Introducing the PG 310, PG 390, and
PG 340
The PG 300 series potentiostat/galvanostat feature state-of-the-art ampli-
fier technology. They include amplification ranges for large currents, new
hardware filters and an external preamplifier design (optional) to reduce
noise levels for small currents. The most significant advance is the complete
software controlled adjustment of the amplifier. This provides the tools
necessary to perform virtually every electrochemical experiment. This also
allows for the simplification and automation of experimental procedures
and gives enormous flexibility for future extensions. The instant automatic
versatile and easy-to-use macro features yield measurements of the high-
est quality, all while retaining the possibility of full manual control of the
amplifier. Therefore, this instrument fulfills the needs of testing industrial
electrodes and scientific research. The versatility of the amplifier and its
superb technical specifications make the PG 300 the instrument of choice
for all electrochemical experiments.
The integration of the PG 300 amplifier with the LIH 8+8 AD/DA interface
and the connected computer constitutes a further step in the minimization
of total recording noise. Complemented by the intrinsic low noise level of
the PG 300 itself with the low current preamplifier, this integrated system
effectively eliminates all interferences because it is fully decoupled by op-
tical isolation that in conventional systems often arise from ground loops.
Furthermore, the full digital control by a computer running our dedicated
software achieves a well-compensated measuring arrangement necessary for
a minimum of noise.
Automatic calibration and testing procedures implemented in the software
control of the PG 300 guarantees exact functioning of the amplifier at all
times. The user can easily run a calibration process whenever it might be
