Chromatography Summary:Helium was employed as the carrier gas at a constant flow rate of 1.5 mL/min and the injector split ratio was adjusted to 1:10. An injection volume of 1 µL was used. The injector, transfer line and ionsource temperatures were maintained at 220, 280 and 250°C, respectively. The oven temperature was programmed at 70°C for 0.2 min, increased at 9°C/min to 270°C where it was sustained for 5 min, and further increased at 40°C/min to 310°C where it was held for 11 min. The mass spectrometer was operated in the electron impact ionization mode at 70 eV. Data were acquired in full scan mode from m/z 40 to 600 with an acquisition rate of 20 spectra per second. To detect retention time shifts and facilitate Kovats retention index (RI) calculation, a standard alkane series mixture (C7-C30) was injected before every batch during sample analysis. This was accompanied by an injection of one pooled QC after every injection of 10 samples.
