Electronic Instrumentation in Chemical Analysis: A Case Study (and Other Examples) From a 20th‐Century “Revolution”

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
A review of advances in chemical analysis brought about by electronic instrumentation. The techniques, and their applications, demonstrate how, collectively, they played a crucial role in transforming the laboratory landscape. If not a relatively recent revolution in one branch of science, it was certainly a transformation.
