Gas chromatographic retention indices of trimethylsilyl derivatives of mono- and diglycerides on capillary columns with non-polar stationary phases.

Mono- and diglycerides play an important role in the metabolism of plants and animals. They are usually constitutive elements of complex mixtures and are not always as main components, which considerably hinder the identification of these analytes. This work communicates about a synthesis of a wide range of esters of glycerol and aliphatic C(6)-C(20) acids and presents gas chromatographic chara...

Gas chromatographic behavior of fatty acid derivatives for mass spectrometry on low-polarity capillary columns

The gas chromatographic properties of four derivatives of fatty acids (FA), namely fatty acid methyl esters, picolinyl esters, N-acyl pyrrolidides and 4,4-dimethyloxazoline derivatives, which contain various structural features (double bonds, branching, hydroxyl group) in their acyl chains have been compared on a low-polarity capillary column with a mass spectrometer as detector. Temperature pr...

Gas Chromatographic Prediction of Poly- Aromatics Retention Indices in Petroleum Crude Oil Sample Based on Retention Indices Matching

Gas chromatographic prediction of poly-aromatics retention indices in a petroleum crude oil based on matching with reported retention indices on the same stationary phases under a similar temperature program was studied. The bases of the matching with reported retention indices for peaks identifications were mentioned. Deconvulated software was used to separate the overlapped poly-aromatic peaks.

Retention-time database of 126 polybrominated diphenyl ether congeners and two bromkal technical mixtures on seven capillary gas chromatographic columns.

The elution order of 126 polybrominated diphenyl ethers (PBDE) was determined for seven different gas chromatographic (GC) stationary phases. The resulting database facilitates selection of the most suitable GC columns for developing a quantitative, congener-specific BDE analysis and the testing of retention prediction algorithms based on structure relationships of GC phases and congener substi...
