DART-MSによる新規デバイスを用いた揮発性成分の高感度分析
In conventional mass spectrometry, there were no high sensitive techniques of analyzing volatile compounds in real time under atmosphere pressure. Direct analysis in real time coupled to mass spectrometry, DART-MS is one of candidate for ambient mass spectrometry for volatile compounds. However, we realized two hurdles as follows: 1) dispersion of ions because of open system, 2) low introduction and concentration of ions into a mass spectrometer due to the structural feature of DART-MS. In this study, we developed and investigated a novel technique to utilize DART-MS for efficient analysis of volatile compounds such as flavors. This result demonstrated ion collection and concentrated introduction with the device were effective for increasing the sensitivity for volatile compounds.
