Episode 77: The Cambridge polarograph model
The history of electrochemistry cannot be written without a major reference to the polarograph invented by Jaroslav Heyrovsky in 1922, which earned him the Nobel Prize in Chemistry, in 1959. In 1948, the polarograph manufactured by the Cambridge Instrument Company, Ltd. arrived at Técnico and was crucial for advances in electrochemistry. The instrument was essential for determining the quantity and quality of certain chemical substances, particularly metals. It was used in medicine, biology, metallurgy, and also for the analysis of organic and inorganic compounds, the study of electrochemical discharges, and the food industry.
