High-resolution molecular imaging ToF SIMS
Matt
Historically ToF SIMS has not been sensitive to intact molecules due to the excessive fragmentation caused by the primary Ion Beam. Now however, thanks to the progress in gas cluster Ion Beam (GCIB) technology over the last decade, sensitivity to intact molecular species in ToF …
Detecting pollutants in a Cherry Blossom leaf
Plant samples such as leaves are a challenging sample for ToF SIMS. Composed of insulating materials such as cellulose (cell walls) and lipophilic coatings (cuticular layer), charge build up can affect measurement quality. Using an electron gun during analysis can alleviate the charging effect and …
A New Tool for Quantum Device Fabrication
July 10th 2018 — A new single ion implantation tool is launched at the UK National Ion Beam Centre. Part of a 3 year project between Ionoptika and the University of Surrey and funded by the EPSRC, the new instrument will enable researchers to create new …
ToF SIMS of Rough or Uneven Samples
A common problem faced by TOF SIMS analysis is loss of peak resolution and mass accuracy on samples with rough or uneven topography. The J105 SIMS does not suffer from these issues, experiencing no loss in mass accuracy across even the roughest of samples The …
Depth Profiling in ToF-SIMS with the J105 SIMS
Depth profiling is a powerful technique in surface analysis for examining interfaces and exploring the 3-dimensional structures of a material, to which SIMS is uniquely suited. Many modern instruments are equipped with a sputter Ion Beam in addition to their primary Analysis Beam for depth …
ToF-SIMS Analysis on Insulating Samples
Performing ToF-SIMS analysis on insulating samples can be particularly challenging. Surface charge can impact the accuracy of the results, or in the worst cases prevent any results being obtained. Thanks to its unique ToF design, the J105 SIMS is capable of imaging highly insulating samples …
