Online coupling of supercritical fluid extraction (SFE) and supercritical fluid chromatography (SFC) with medium vacuum chemical ionization (MVCI) mass spectrometry (MS) has been investigated. This novel analytical method has great potential to quantitate lipophilic small molecules contained in an extremely small sample, such as a cell. Obtained lower limit of quantitation (LLOQ) for arachidonic acid and arachidic acid were 1.2 and 2.7 fmol, respectively. Sixteen free fatty acids were quantified from 100 nL human pool serum, with a repeatability of 0.1 to 16% of relative standard deviation.
