A workflow for the metabolomic/metabonomic investigation of exhaled breath using thermal desorption GC-MS.


BACKGROUND Confounding factors in the analysis of human breath by thermal desorption GC-MS are reviewed, with special emphasis on the high water levels encountered in human breath samples. RESULTS Multilinear regression optimization of breath sampling factors, along with the selection of ubiquitous sample components used as retention-time standards… (More)
