[TOF-SIMS] Time-of-Flight Secondary Ion Mass Spectrometry

This is a method for structural analysis of the sample surface. Due to its sensitivity to the surface compared to other analytical devices, it is suitable for identifying organic contaminants on the very surface.

This is a method for structural analysis of sample surfaces. It is suitable for identifying organic contamination on the very surface due to its sensitivity compared to other analytical devices. Using a sputter ion source, it is possible to analyze the distribution of inorganic and organic materials in the depth direction. - Structural analysis and identification of organic and inorganic compounds are possible. - Coordination data from foreign substance inspection devices can be linked. - Qualitative analysis is possible from micron-order microforeign substances to several centimeters. - It is possible to analyze the very surface with high sensitivity. - Image analysis is possible. - Qualitative analysis of depth direction analysis is possible.

basic information

By reducing the amount of ion irradiation at one time, it becomes possible to maintain the molecular state of the surface and generate secondary ions. The obtained secondary ions are analyzed using a Time-of-Flight mass spectrometer.
