The Air Liquide Gas Encyclopedia gives a quick access to physical, chemical and safety properties of the main gases. It includes 64 molecules.
Besides a classical search engine on raw material formula, chemical name or UN transportation code, an exploration tool allows access to each molecule data sheet. The app is enriched by a gas comparator (up to 3 gases displayed simultaneously), a unit conversion wheel, and gas/liquid conversion. Molecules can be filtered by major hazards, material compatibility and applications.
The Gas Encyclopedia also highlights main applications of each gas by industrial sectors.
