64 molecules to (re)discover
1976: Air Liquide teamed up with Elsevier to publish the first Gas Encyclopedia. A considerable amount of work was done by the Group’s Research and Development experts, who collected and selected data on topics as broad as physical properties, instructions for use, compatibility with various materials, and the uses of more than 100 molecules.
Practical and precise, this Encyclopedia rapidly became a key reference for many users, leading to updated editions in 1985 and 2002.
Today, the Gas Encyclopedia is still a highly-regarded tool for academics as well as industrialists. Available online since 2002, it has been further improved since with additional practical tools such as the gas/liquid converter to facilitate the work of its users. These efforts have paid off, with the online Encyclopedia generating more than a million visits a year. In 2013, a Gas Encyclopedia app for tablets focusing on 64 molecules was made available, offering mobility and greater user friendliness. This version integrates a universal converter and a molecule comparison tool.
Fully revamped and launched in 2017, the new Gas Encyclopedia website is now available across digital media (mobile phones, tablets, laptops). Available in French and English, this site is designed to be used by anyone, anywhere. It offers all functionalities for the 64 molecules, making this application a success, especially the comparison and conversion tools. The data are regularly updated, ensuring that the most complete and up to date information is available. A healthcare gas application has also been added.
This initiative illustrates the commitment of the Air Liquide Group and its scientific community, the m-Lab (molecule lab), to the development and sharing of the scientific knowledge on essential small molecules for life, matter and energy.
Initiated by R&D in 2015, the m-Lab is Air Liquide’s in-house scientific community created to facilitate open innovation with our customers and partners. This community can be contacted with LinkedIn.
