Low oxygen transmission imaging system |
| abstract |
A method of detecting the permeability of an article to oxygen is disclosed. A fluorescent redox indicator, preferably riboflavin, is dispersed in a carrier and placed on an impermeable substrate. The article to be measured is placed adjacent to the carrier. Residual oxygen is removed, the redox indicator is photoreduced, the article and carrier are exposed to oxygen, and the indicator is exposed to UV light. |
