ToF-qSIMS Workstation

Innovative Time of Flight Quadrupole SIMS System

  • Model: ToF-qSIMS
  • Manufacturer: Hiden Analytical

The Hiden TOF-qSIMS system is designed for surface analysis and depth profiling applications of a wide range of materials including polymers, pharmaceuticals, superconductors, semiconductors, alloys, optical and functional coatings and dielectrics, with measurement of trace components to sub-ppm levels.

Application 

  • Contamination with silicone: top monolayer specific analysis  
  • Surgical stent: imaging, depth profiling and surface specific analysis to characterise the near surface  
  • Contamination: imaging and mass spectra to locate and identify surface contamination 
  • Nuclear materials: identification of isotopically rich materials using bulk composition mass spectra  
  • Pharmaceuticals: identification of molecular signals using static SIMS on powders 

Category:

The new Hiden TOF, time of flight analyser enhances SIMS to give the user the best of the dynamic range from high performance quadrupole SIMS together with the advantages of parallel data collection and molecular fragment analysis from time of flight SIMS, TOF-SIMS.

The TOF-qSIMS capability enables hyperspectral imaging for spatially resolved detailed materials analysis.

The TOF-qSIMS system offers the comprehensive capabilities of static TOF-SIMS, and high dynamic range depth profiling from the quadrupole SIMS.

Fully integrated and optimised for high performance SIMS analysis, the TOF-qSIMS Workstation system includes a multi-port UHV chamber, TOF-SIMS analyser, Hiden’s MAXIM quadrupole SIMS analyser, IG20 gas primary ion gun, a Cs metal Ion gun and a sample holder designed to accommodate the broadest sample range.  High sensitivity SNMS mode is included for quantitative analysis of metallurgical thin films, conductive and non-conductive oxides and other alloy materials and coatings. Facilities for SIMS enhancement including oxygen flood, electron charge neutralization and vacuum bakeout are included as standard.

The SIMS Mapper PC software option provides for mapping with 2D and 3D view capability over the sample area. Electronic gating is included for optimised high dynamic range depth profiling. The TOF SIMS analysis capability includes full spectral analysis, pixel by pixel across the sample image.
