Nano Secondary Ion Mass Spectrometer

Nano Secondary Ion Mass Spectrometer Leading-edge Equipment Home

Equipment Introduction

The Nano Secondary Ion Mass Spectrometer (Nano SIMS, model: Nano SIMS 50), can perform the quantitative imaging process with focused 50-nm primary ion beams for the distribution of trace elements in materials. It is operated as national coutilization equipment.

Characteristics of the Equipment

  • World’s best spatial resolution (50 nm) in a secondary ion mass spectrometer
  • Multiple detection of impurity elements in a small area
  • High-sensitivity imaging of light elements (including hydrogen)

Representative Research Case

A Study on the correlation between precipitation and intragranular fracture in austenite stainless steel by using NanoSIMS

The purpose of this study is to investigate the structural and mechanical properties of austeniteof austenite stainless steel used in power plants, and the correlation between precipitation and intra-granular fracture. Nano SIMS was used to determine the precipitation of phosphorus and sulfur in the prior austenite grain boundary (PAGB), which made an intra-granular fracture in the coarse-grained heat affected zone (CGHAZ).
