A semiautomatic polarograph: A low cost instrument for student use

Abstract

Presents the design of a semiautomatic polarograph suitable for introductory analytical chemistry.

Polarographic Theory, Instrumentation, and Methodology

“…Papoff, Grifone, and Zuliani (170) have described a pen-recording polarograph wfith a wdde range of scanning rates. Drake and Johnston (50) pro-pose a semiautomatic polarograph in which current readings are plotted manually on a chart coupled with the voltage scan. The apparatus is said to be convenient for instructional purposes.…”
