Title:
MASS SPECTROMETRY METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/150900
Kind Code:
A1
Abstract:
In a mass spectrometry method, a deuterium-resolved mass spectrum of a gas sample comprising volatile metabolites that have been excreted from a human or animal subject (50) after ingestion of deuterated water is determined. The deuterium-resolved mass spectrum to determine a presence or amount of at least one deuterated metabolite. Also disclosed is a corresponding mass spectrometry system.
