## Abstract An HPLC non‐aqueous reversed‐phase separation system was adapted for analyzing insect triacylglycerols (TAG). The method uses two conventional Nova‐Pak C18 columns connected in series, for a total length of 45 cm. The mobile phase gradient is mixed from acetonitrile and 2‐propanol, and
High performance liquid chromatography in conjunction with atmospheric pressure chemical ionization mass spectrometry (HPLC/APCI-MS) enables the positional isomers of individual triacylglycerols in mixtures to be identified. Application of HPLC/APCI-MS to the analysis of soybean oil allowed thirty n
## High -performance liquid chromatography/atmospheric pressure chemical ionization mass spectrometry (HPLC/APCI-MS) is a very promising approach to structural investigations of positional isomers and stereoisomers. This method was applied successfully to stereoisomeric norditerpenoid alkaloids dif
Ceramides are intermediates in the biosynthesis of membrane sphingolipids. These biomolecules are also important as second messengers in signal transduction pathways controlling cell growth. We have developed two reversed-phase high pressure liquid chromatography (RPHPLC) techniques for identificati
