  • Feb 2013
The present review shows the utility of using mass spectrometry (MS) in obstetrics and gynecology. In this review different gas chromatography / mass spectrometry and liquid chromatography / mass spectrometry methods developed before to be used in obstetrics and gynecology are described. These methods are very useful to determine different hormones...

Context 1
... were extracted using a method proposed by Pragst [18,19] which include head space solid microextraction (HS-SPME) and gas chromatography / mass spectrometry. The deuterated standards of few fatty esters were added to be used as internal standards. [11,16,17] A standard curve was obtained using blank meconium and the four esters presented in Fig. 1. These fatty esters (1-4) were used at different concentrations ...

... fiber was injected into a gas chromatograph connected with a mass spectrometer operated in electrospray ionization mode (ESI). The detection limits of the fatty acid ethyl esters were 15 ng g -1 for the compounds 1, 3 and 4, and 50 ng g -1 for the compound 2 ( Fig. ...
