摘要:
A system is described which is entirely composed of commercially available instruments. The construction of a rotating cell with two compartments is described in detail. It is furthermore shown that a differential amplifier, although applicable in most cases, cannot be used in the case of small signals on a large background because of its small dynamic range. This difficulty can be overcome by incorporating a lock‐in amplifier in the system.
