This study successfully detects n-hexanal in vehicle interior air using a combination of gas chromatography and dual-polarity ion mobility spectrometry. By employing quality tools to identify the primary factors influencing the testing process, various Design of Experiments (DOE) were conducted under different conditions to establish a gas chromatography-ion mobility spectrometry (GC-IMS) method for detecting n-hexanal in vehicle air. This method was then extended to detect other volatile organic compounds (VOCs), such as benzene, toluene, ethylbenzene, xylene, acetaldehyde, and acrolein, in vehicle interiors.

摘要

This study successfully detects n-hexanal in vehicle interior air using a combination of gas chromatography and dual-polarity ion mobility spectrometry. By employing quality tools to identify the primary factors influencing the testing process, various Design of Experiments (DOE) were conducted under different conditions to establish a gas chromatography-ion mobility spectrometry (GC-IMS) method for detecting n-hexanal in vehicle air. This method was then extended to detect other volatile organic compounds (VOCs), such as benzene, toluene, ethylbenzene, xylene, acetaldehyde, and acrolein, in vehicle interiors.
