Issue Highlights

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 Matrix-Assisted Laser Desporption/ Ionization Mass Spectrometry: Insturmentation and Applications by Muddiman, Bakhtiar, Hofstadler, and Smith.

Cover design by Nina Hofstadler of The Design Consortium, Richland, WA..

The cover was designed by Betsy True.
