Imaging of Lipids in Spinal Cord Using Intermediate Pressure Matrix-Assisted Laser Desorption-Linear Ion Trap/Orbitrap MS

A hybrid linear ion trap/Orbitrap mass spectrometer was used to perform tandem mass spectrometry (MS/MS) experiments and high-resolution mass analysis of lipids desorbed from nerve tissue. A dramatic improvement in mass spectral resolution and a decrease in background are observed in the spectra col...
