Qualification and quantification of seventeen natural steroids in plasma by GC-Q-MS and GC-IT-MS/MS.
Studying the plasma steroid profile offers information about the possible existence of endocrinological alterations. This study describes the development and validation of gas chromatographic-mass spectrometric and gas tandem mass spectrometric methods for the simultaneous identification of 17 steroid hormones in human plasma using five different solvents. The n-hexane/ethyl acetate solvent mix...

متن کاملComprehensive Screening, Confirmation, and Quantification of Organic Pesticides in Foods by GC–MS and LC–MS
and distribution have become truly international businesses. When we dine out, the fish might come from Japan, the rice from Australia, the spices from China, and the strawberries from Mexico. We take it for granted that the food we eat is safe and free from contamination that could make us seriously ill. One of the 20th-century advancements that made this cornucopia possible was the developmen...
متن کاملDetermination of Alprazolam in Rabbit Plasma by GC-MS Method
This paper describes a gas chromatography-mass spectrometry (GC-MS) method for determination of alprazolam in rabbit plasma. Alprazolam and internal standard (IS) medazepam were extracted from plasma by using liquid-liquid extraction method. The samples were separated by GC on a DB-5MS analytical column and determined by a quadrupole mass spectrometer detector operated under selected ion monito...
