Elucidation of the triglycerides in fish oil by packed-column supercritical fluid chromatography fractionation followed by capillary electrochromatography and electrospray mass spectrometry

Recent progress in capillary electrochromatography

“…Many reports on CEC-MS have focused on the characterization of the coupling between the two techniques [155, 201±206]. CEC-MS has been used recently for several applications including analysis of samples containing, for example, peptides and amino acids [130,156,183,204], preservatives is pharmaceutical creams [127], metal ions [207], triglycerides and fatty acids [204,208], DNA [209±211], tags from combinatorial organic synthesis [212], drug candidates [213], and fatty acids and vitamins [204], among others.…”

Ultrahigh performance supercritical fluid chromatography of lipophilic compounds with application to synthetic and commercial biodiesel

“…For example, TAGs have been analyzed by packed column SFC using for example 2-ethylpyridine [9] and silver-ion exchange [10] stationary phases. Using a reversed phase stationary phase such as octadecylsilica [11], the SFC separation may be based upon carbon number (i.e. total number of carbons in all fatty acids) and/or on the number of double bonds.…”

Off-line coupling of non-aqueous reversed-phase and silver ion high-performance liquid chromatography–mass spectrometry for the characterization of rice oil triacylglycerol positional isomers

“…Several multi-modal chromatographic systems have been described: silver ion LC/reversed-phase LC [34], reversed-phase LC/silver ion LC [35], capillary SFC/capillary GC [36], Ag-pSFC/RP-CEC [37], comprehensive two-dimensional liquid chromatography (first dimension: Ag-; second dimension: RP-) [38], automated off-line pSFC (RP) × pSFC (Ag)/MS [39].…”
