(Monday's recorded broadcast)

A modern method of chemical analysis by I.S. Longmuir, M.B., B.Chir., Senior Lecturer in Biochemistry, Institute of Diseases of the Chest, University of London.

Technologists strive to devise the continuous flow of production rather than to make things in batches. This often calls for continuous monitoring, and for this polarography is particularly suitable.
Although it had its origins in work carried out by Faraday in London a hundred years ago, polarography was invented by Jaroslav Heyrovsky of Prague. Dr. Longmuir, who visited Professor Heyrovsky recently, speaks of some of the work he saw.
