Secondary ion mass spectrometry dynamic

Dynamic Secondary Ion Mass Spectrometry (Dynamic SIMS)... 

Other technique—for example, dynamic secondary ion mass spectrometry or forward recoil spectrometry—that rely on mass differences can use the same type of substitution to provide contrast. However, for hydrocarbon materials these methods attain a depth resolution of approximately 13 nm and 80 nm, respectively. For many problems in complex fluids and in polymers this resolution is too poor to extract critical information. Consequently, neutron reflectivity substantially extends the depth resolution capabilities of these methods and has led, in recent years, to key information not accessible by the other techniques.

Material properties often depend on the constituents of inclusions as small as a few micrometers large or surface layers with a thickness of 0.1-100 nm. From the 1970s onward, microanalysis has become a major challenge. Initial methods such as electron probe X-ray microanalysis (EPXMA) or dynamic secondary ion mass spectrometry (SIMS) determine elements at the microscopic scale, but charge buildup and beam-induced sample damage hamper their application to nonconducting organic materials.

The chemical mapping of simple ions such as C, Na, and have been applied to the TOF-SIMS analysis of biological samples of organs, tissues, and cells [22-27,89,90], and 3D images of the elemental distributions [91] have also been obtained. In addition, lateral and 3D distributions of Na+, K+, Ca+, and isotope-labeled elements in cells can be obtained with dynamic secondary ion mass spectrometry (DSIMS) imaging techniques [91,92].

Molecular aggregation structure of the PS-PFACg diblock copolymer films along the normal direction to the surface was also examined by dynamic secondary ion mass spectrometry (DSIMS), which is a well-established tool for the depth profiling of polymer materials. The PFA weight fraction at the depth of z by DSIMS was given as follows.
