COMMENT: 1 micro litter of limonene (liquid) was placed on glass capillary.
COMMENT: (R)-(+)-Limonene was purchased from Wako 124-03892.
COMMENT: This record was created by the financial support of MEXT/JSPS KAKENHI Grant Number 16HP2005 to the Mass Spectrometry Society of Japan.
COMMENT: Direct analysis in real time (DART) is a method of atmospheric pressure chemical ionization (APCI). Protons, H+, generated by glow discharge ionization (-5 kV) of the He gas in the ionization chamber, DART-SVP (IonSense Inc., MA, USA), were major reactant ions for the chemical ionization of samples.
COMMENT: 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).
