Abstract
- We applied negative ion APCI mass spectrometry to the quantification of simulated breath containing air, water vapor, N2O and CO2.
- We added CHCl3 to mimic the influence of halocarbons associated with the breath of anesthetized subjects.
- Both SO2â and SO3â were observed to be sensitive to H2S down to about 1Â ppt (trillion). The observed ratio of [SO2â] to [SO3â] was found to be the most useful monitor of H2S.
- SHâ was found to be suppressed by CO2 and so unsuitable for H2S quantification in breath.
