Abstract
Thermospray mass spectrometric detection is applied for alprenolol and its isomeric (E and Z) ketoxime analogues separated by reversed-phase high-performance liquid chromatography. The thermospray process results in high-intensity [M+H]+ ion formation. This method of detection provides high level of molecular specificity, and offers advantages for the identification of the stereoisomeric oximes due to the unique fragmentation pattern of the spectra.
