PhD and then became a lecturer in chemistry at St Bartholomew's Hospital .

Armstrong was from 1871 professor of chemistry at the London Institution. He became an Assistant Examiner in Chemistry at the University of London . In 1911 he was forced to resign as professor of chemistry at the Central Technological College. From 1914 he worked as a freelance chemist.

From 1875 to 1893 he was secretary of the Chemical Society, its president in 1894/95 and then vice-president. In 1876 he became a member of the Royal Society.
