TOF-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 کاملReconstructing accurate ToF-SIMS depth profiles for organic materials with differential sputter rates.
To properly process and reconstruct 3D ToF-SIMS data from systems such as multi-component polymers, drug delivery scaffolds, cells and tissues, it is important to understand the sputtering behavior of the sample. Modern cluster sources enable efficient and stable sputtering of many organics materials. However, not all materials sputter at the same rate and few studies have explored how differen...

متن کاملDevelopment of PNA microarrays for gene diagnostics with TOF-SIMS
We have used time-of-flight secondary ion mass spectrometry (TOF-SIMS) to examine different immobilization processes of peptide nucleic acid (PNA) and their influence on the hybridization efficiency of unlabeled DNA fragments to complementary PNA. Two different approaches have been used to immobilize PNA onto Au surfaces. One method was to immobilize thiolated PNA in a single step reaction to t...
متن کاملApplications of TOF-SIMS in Planetology
In planetology the analysis of micrometer-sized samples like, e.g., inclusions in meteorites, interplanetary dust, and presolar grains has become more and more important. This requires techniques with high lateral resolution, no or little sample destruction, and high sensitivity. To still obtain unbiased information on this kind of samples a technique or a suite of techniques has to be selected...
