Chip mass spectrometry

WebTo date, mass spectrometry (MS) turned out to be the method of choice for analyzing individual molecular lipid species. In lipidomics, two main approaches can be distinguished. In the “shotgun” approach, (sphingo)lipids are analyzed by MS out of crude lipid extracts without previous chromatographic separation [19–24]. WebJan 1, 2015 · Here, ϕ is the work function of the filament material, and A is Richardson’s constant, given by A = 4πm e k 2 e/h 3, where m e is the electron mass and h = 6.62 ⋅ 10 −34 Js is Planck’s constant. The field-induced term is Δϕ = (eE/4πε 0) 1/2, where ε 0 = 8.85 ⋅ 10 −12 F/m is the vacuum permittivity. Because of the exponential variation above, …
