In a sphingomyelin-enriched sample of polar lipids from bovine milk, molecular species of intact sphingomyelin were separated by normal-phase high-performance liquid chromatography and detected by mass spectrometry (MS) for structural information. First, by using electrospray with positive ionizatio
The performance of electrospray ionization and atmospheric pressure chemical ionisation (APCI) for the analysis of carotenoids was investigated. On our instrument, APCI produced spectra which were readily interpreted, and the positive-ion mode proved applicable to all of the compounds. The separatio
A sensitive and specific liquid chromatographic method coupled with tandem mass spectrometry was developed for the quantification of amlodipine in human and rat serum, which is a dihydropyridine derivative with calcium antagonist activity.
