On the use of quadrupole mass spectrometric detection for flow modulated comprehensive two-dimensional gas chromatography.

Flow modulated comprehensive two-dimensional gas chromatography with simultaneous flame ionization detection (FM GC×GC-FID) and quadrupole mass spectrometric detection (FM GC×GC-qMSD) was applied to the analysis of a quantitative reference standard sample covering the C5-C14 hydrocarbon range and a kerosene sample. This study reports the influence of the data acquisition frequency (DAF) of the qMSD on the qualitative and quantitative data. The DAF was varied between 5.

On the use of ionic liquid capillary columns for analysis of aromatic hydrocarbons in low-boiling petrochemical products by one-dimensional and comprehensive two-dimensional gas chromatography.

One-dimensional and comprehensive two-dimensional flow modulated gas chromatography with simultaneous flame ionization and mass spectrometric detection were applied for the identification and quantification of benzene, toluene, ethyl benzene and xylenes (BTEX) as well as of all C9-C11 aromatic hydrocarbons in the low-boiling petroleum products gasoline, reformate and fluid catalytic cracking (FCC) samples. GC×GC experiments were performed on two reversed phase polarity column sets namely SLB-IL100 (25m×250μm i.d.
