Critical Assessment
of Small Molecule Identification

The experimental and computational mass spectrometry communities are invited to participate in the fifth round of an open contest on the identification of small molecules from mass spectrometry data.

This year the contest will test the applicability of MS and MS/MS on natural products chemistry identifications. With 45 (Category 1) and up to 243 (Categories 2&3) natural products challenges - including a few tricky ones - there’s something for everyone!

CASMI 2017 is organised by Dr. Dejan Nikolic (University of Illinois at Chicago, USA), Dr. Nir Shahaf (Weizmann Institute of Science, Israel), Dr. Emma Schymanski (Eawag, Switzerland) and Dr. Steffen Neumann (IPB Halle, Germany).
