In this paper we report a method for the comparative analysis of volatile organic
compounds (VOCs) at physiologically representative concentrations by different analytical
methods Standard aqueous solutions of acetone, ethanol, methanol, 1-propanol, 2-propanol
and acetaldehyde were prepared by adding a specific mass of compound to a known volume
of water, calculated using published Henry’s law constants for individual compounds.
Headspace concentrations are thus known from established partitioning from dilute
aqueous phase in accordance with Henry’s law. Selected Ion Flow Tube Mass Spectrometry
(SIFT-MS), Proton Transfer Reaction Mass Spectrometry (PTR-MS), and Gas Chromatography–Mass
Spectrometry (GC–MS) coupled to thermal desorption have been used to study and evaluate
the performance of the instruments in the analysis of these VOCs. These analytical
techniques have been widely used in the identification and quantification of trace
concentrations of VOCs in biological samples. Quantitative determination of VOC concentration
was achieved and the performance of the instruments compared with one another. Calibration
curves are given within the range 10<sup>1</sup>–10<sup>3</sup> ppbv. |
