A Case Study of Characterization and Continuous Monitoring of Trace Odorants in the Shinshu University School of Medicine Hospital ICU Room Air

Characterization of trace amounts of odorants in the Shinshu University School of Medicine Hospital ICU room (ca.257m2) air was carried out by gas chromatography and API-Mass spectrometry. The main component of the oxygenates in the ICU air was ethanol, 3.53ppm, however, the data was less than the odor recognition threshold value (6.1ppm).
