Popis

Application

Learn more in the Product Information

It is used for the analysis of D2/E2-isoprostanes using negative ion chemical ionization-gas chromatography/mass spectrometry (NICI-GC/MS). Fatty acids may be converted to pentafluorobenzyl esters using PFG-Br and diisopropylethylamine during determination of fatty acids using NICI-GC/MS.
