Abstract:Breath ammonia is an important biomarker linked to liver malfunction. Acetone is the most abundant compound in the breath, acts as major interference for selective detection of ammonia gas. Here, a novel method based on viscosity modulation of the silicone oil absorbent is reported for selectivity improvement of ammonia over acetone gas. ATD-GC-MS and T201 ammonia analyzer are used to measure the absorption of acetone and ammonia respectively into the silicone oil. The absorption of ammonia and acetone gas is … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
