リアルタイム直接質量分析イオン源DART（Direct Analysis in Real Time）質量分析法の応用

抄録

We introduce applications of Direct Analysis in Real Time (DART) ion source, used in open-air at ground potential under ambient conditions, coupled with time-of-flight or quadrupole mass spectrometer.
DART was developed in 2005 as a new type of atmospheric pressure ion source. One of the most interesting features of DART is that researchers can access the place of ionizing point directly. It means we can observe real-time spectra of a sample at ground potential under ambient condition. In this paper, we will introduce the principles and features of DART ion source and some applications of DART mass spectrometry.
