Quality criteria for chromatographic analytical systems of polyunsaturated fatty acids metabolites.

The most powerful technique for eicosanoids identification is gas chromatography prior to mass spectrometry. Results are highly dependent upon the choice of appropriate gas chromatographic systems; the critical point of the system being the quality of the column. Our work is intended to provide a general overview of open tubular capillary columns which can be used for separation, identification and quantification of eicosanoids.
