About the Cover:
The cover depicts Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry, or MALDI. An incoming laser pulse hits a sample and ejects molecules of different molecular weight, which become separated in time. The background image is a photomicrograph of the crystalline surface of 2,5-dihydroxybenzoic acid. Crystal heterogeneity (size and shape), as shown in the image, gives rise to different analyte ion signals at different positions on the surface of the same sample. See the article by Muddiman, Bakhtiar, Hofstadler, and Smith on page 1288.
