One micro litter of the liquid sample was dropped in a 10 mL glass vial. The vial was placed under the DART ion source.
Direct analysis in real time (DART) is a method of atmospheric pressure chemical ionization (APCI). Protons, H+, generated by glow discharge ionization of the He gas in the ionization chamber, DART-SVP (IonSense Inc., MA, USA), were major reactant ions for the chemical ionization of samples.
The interface introducing the product ions to the mass spectrometer was Vapur Interface (AMR. Inc., Tokyo, Japan). The pressure in the interface was 710 Torr (96.3 kPa).
1 mg of azulene was placed on glass capillary. The capillary was placed in the gas flow that ran from the ion source.
Azulene was purchased from TCI A0634.
This record was created by the financial support of MEXT/JSPS KAKENHI Grant Number 16HP2005 to the Mass Spectrometry Society of Japan.
