Investigation of Hydrogel Contact Lenses with EnviroESCA
This application note presents how EnviroESCA can be used to analyze the surface of water filled hydrogels, such as contact lenses like in the present study as an example for medical and biomaterials. The advantage of such investigations under non ultrahigh vacuum conditions is demonstrated and results from wet and dry samples are compared.
