title: Gas-liquid chromatography-mass spectrometry of thromboxane B2 and its detection in semen and human aorta by selected ion monitoring.
abstract: The gas-liquid chromatographic and mass spectrometric properties of some derivatives of thromboxane B2 methyl ester have been examined. Mass spectra were usually more informative at lower electron energies. The O-methyl- and O-n-propyloxime tri-trimethylsilyl ethers, and the tri-tert.-butyldimethylsilyl ether were used for selected ion monitoring (SIM). Thromboxane B2 was detected by SIM in bovine semen and in human aorta.
