متن کاملTOF-SIMS in Cosmochemistry
Time-of-flight secondary ion mass spectrometry (TOF-SIMS) was introduced into cosmochemistry about a decade ago. Major advantages of TOF-SIMS compared to other ion microprobe techniques are (a) parallel detection of all secondary ions with one polarity in a single measurement – both polarities in subsequent analyses, (b) high lateral resolution, (c) sufficient mass resolution for separation of ...
متن کاملAccounting for Poisson noise in the multivariate analysis of ToF-SIMS spectrum images
Recent years have seen the introduction of many surface characterization instruments and other spectral imaging systems that are capable of generating data in truly prodigious quantities. The challenge faced by the analyst, then, is to extract the essential chemical information from this overwhelming volume of spectral data. Multivariate statistical techniques such as principal component analys...
متن کاملSurface Characterization of Polymer Blends by XPS and ToF-SIMS
The surface properties of polymer blends are important for many industrial applications. The physical and chemical properties at the surface of polymer blends can be drastically different from those in the bulk due to the surface segregation of the low surface energy component. X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary mass spectrometry (ToF-SIMS) have been widely used...
متن کاملToF-SIMS studies of Bacillus using multivariate analysis with possible identification and taxonomic applications
In this paper we discuss the application of ToF-SIMS with an Au3 + primary ion beam, combined with principal components analysis (PCA) and discriminant function analysis (DFA) for the identification of individual strains of two Bacillus species. The ToF-SIMS PC-DFA methodology is capable of distinguishing bacteria at the strain level based on analysis of surface chemical species. By classifying...
