Desorption electrospray ionization mass spectrometry imaging (DESI-MSI) can record 2D distribution of polar lipids in tissue slices at ambient condition. However, sensitivity of DESI-MSI for nonpolar lipids is restricted by low ionization efficiency and severe ion suppression. Here, a compact post-photoionization assembly combined with DESI (DESI/PI) was developed for simultaneous imaging polar and nonpolar lipids in tissue sections by switching off/on a portable krypton lamp. Compared with DESI, higher signal intensities of nonpolar com
