The electrolytic test for detection of arsenic alone and in the presence of other metals.
A historical account is given of the development of the electrolytic generation of arsine in the Marsh test, showing how it was early realized that a step in an analytical procedure could be advantageously replaced by a more efficient one. It also shows that well-designed apparatus never really becomes outmoded.
