In the Laboratory
A Computer-Controlled Bipolar Pulse Conductivity Apparatus
N. Papadopoulos and M. Limniou
Department of Chemistry, Aristotle University, 54006 Thessaloniki, Greece

February 2001
Vol. 78 No. 2
p. 245
Abstract
A laboratory apparatus for ion conductivity measurements is described. This apparatus is controlled by a personal computer. We use commercial interface A/D D/A cards with very satisfactory results. The accuracy of this instrument is 0.5 percent. It is simple and inexpensive enough for use in the undergraduate laboratory. In addition, the use of computer-interfaced instruments gives the students the feeling of modern instrumentation.
