Microbore high performance liquid chromatography-ion spray mass spectrometry is demonstrated for the determination of peptides. The ion spray mass spectra of peptides contained primarily only (M+nH)"+ ions (n is the degree of protonation). The linearity for a dilution series of leucine enkephalin wa

## Abstract A rapid, sensitive and specific high‐performance liquid chromatography–electrospray ionization mass spectrometry (LC‐ESI‐MS) method has been developed and validated for the determination of oxatomide in human plasma. Flunarizine hydrochloride was employed as the internal standard (IS).
This new reaction should be applicable to other iodoalkynes. In this context, we have found that 1-( 1-cyclohexeny1)-2-iodoethyne (1 e) can also be dimerized by reaction with Ipy2BF4/HBF4 in CH,CI, (Scheme 3). Running the reaction n Q C Scheme 3. Synthesis of a cross-conjugated (dieny1)enyne by the
## Abstract A method for the quantification of clavulanic acid in calf plasma using high‐performance liquid chromatography combined with electrospray ionization (ESI) mass spectrometry, operating in the negative ionization mode (LC‐MS/MS), is presented. Sample preparation includes a simple and fast
