Аннотация:A method is proposed for determining semivolatile organic compounds in exhaled breath conden
sate by gas chromatography–mass spectrometry (GC–MS) with preliminary liquid–liquid extraction and
adsorption preconcentration of analytes from the extract obtained. The introduction of a significant portion
of the resulting preconcentrate (up to 100 мL) into the chromatograph injector substantially lowered the
detection limits for analytes. The experiment revealed a number of substances that have not been previously
identified in the exhaled breath condensate. A list of these compounds is presented in the article.
