His work led him to conclude that chemical combinations happen between particles of different atomic weights, a groundbreaking concept that outshone the assumptions of many of the ancient Greeks. Dalton's interpretation of atomic theory maintained that atoms are combined in chemical reactions, but also that they can be separated and rearranged.

However, Dalton concluded that the atoms themselves could not be separated or created. Different elements' atoms can combine in set ratios to produce new compounds. One of his most important contributions is also his work on the principles of volumetric analysis.
