The mass selective detector was equipped with a quadrupole
mass analyzer and was operated in electron ionization
mode at 70 eV. The MS was operated in full scan mode
(41–500 amu at 3.2 scan/s), and data were evaluated by MSD
ChemStation D.02.00.275 software (Agilent). The identification
of the compounds was carried out by comparing retention
times, retention indices and recorded spectrawith data known
from the literature [19–21] and the NIST 05 library were also
consulted.
