WebHelium is a Python library for automating web sites. It is based on Selenium-python. Selenium is great, but difficult to use. Helium wraps around Selenium to give you a simpler API. Helium’s name comes from being a lighter chemical element than Selenium. For a quick overview of Helium’s features, please see the project home page.

Application of this method is demonstrated with three case examples, encompassing an array of different biological matrices. PMID:22337780. Schaff JE et al; J Anal Toxicol 36 (2): 112-5 (2012) Web1. Heliox mixtures in respiratory treatments for asthma, bronchitis and other lung deficiencies By combining helium and oxygen, doctors produce a heliox gas mixture (roughly 79% helium and 21% oxygen), useful for the effective treatment of respiratory ailments like asthma and emphysema. This works by lowering overall airflow resistance.
