Problems in Standardization of 252Cf Fission Fragment Induced Desorption Mass Spectrometryboratories. Before applying a new analytical technique for quantitative measurements one should investigate the sensitivity and reproducibility of the given equipment [2,3]. Besides standardization of this time-of-flight mass spectrometry is discussed.

Secondary Ion Emission from Metals Under Fission Fragment Bombardmenton is usually not taken into consideration. Using empirical ionization probabilities from low-energy SIMS experiments the yields of metal ions agreed reasonably with values calculated by means of linear cascade theory [2].

Temperature Dependence of Secondary Ion Emission from Phenylalanineions as well as admixed substances, pH value of the solution and the substrate material may give rise to hazardous modifications of the spectra. Therefore, the recognition of substance and the determination of quantities may be seriously aggravated even in case of low order amounts of accompanying materials.

Mass Spectrometry of Secondary Ions: Polymers, Plasticizers and Polycyclic Aromatic Hydrocarbons primarily for the study of nonvolatile and thermally labile compounds. Two of these techniques, SIMS and FAB, and their application to the analysis of polymers, plasticizers and polycyclic aromatic hydrocarbons are the subject of this contribution.
