Fundamental aspects, instrumentation and analytical applications are considered in this 4th international conference on ion formation from organic solids (IFOS IV), concentrating on the developing of desorbed neutral particles. Theoretical aspects are discussed as well as analytical applications of the different techniques applied for the ionization organic materials and the different techniques available for the identification of desorbed neutral particles are also looked into.
