Advantages of the icpTOF

The icpTOF is an inductively coupled plasma mass spectrometer (ICP-MS) that couples the source and interface hardware of a Thermo Scientific iCAP RQ to a TOFWERK TOF mass analyzer.  The iCAP RQ hardware provides versatile sample introduction, robust ICP, simple access to cones and lenses and the Q-cell technology. The TOF adds simultaneous all-element detection, linear response and mass resolving power >6000, while maintaining QMS-equivalent sensitivity.   With high-speed mass spectral acquisition and simultaneous analysis of all isotopes, the icpTOF is the ideal ICP-MS detector for multi-element single particle analysis or fast laser ablation imaging.

  • All the elements. All the time. The icpTOF always records complete mass spectra, so you never miss an analyte or interference signal.
  • High mass resolution. The icpTOF 2R has a mass resolving power of 6000 allowing you to separate interfering ions.
  • Precise isotope ratios. The icpTOF simultaneously measures all isotopes, thus eliminating the susceptibility of your measurements to source and sample fluctuations.  Precision approaches statistical limits.
  • High speed detection. The icpTOF records a complete mass spectrum every 30-50 µs making it the optimum detector for fast transient signals such as individual nanoparticles, fluid inclusions and laser ablation pixels.

icpTOF and icpTOF 2R Models

The icpTOF and the icpTOF 2R couple a TOFWERK time-of-flight (TOF) mass analyzer to the source and interface hardware of a Thermo iCAP RQ.   The icpTOF 2R key design modification is a lengthening of the TOF ion drift chamber, which doubles the mass resolving power from >3000 (icpTOF) to >6000 (icpTOF 2R).  The 2R is now the choice for applications that demand separation of difficult isobaric interferences.

Increased Flight Path for Improved Resolving Power

  • Both icpTOF models include the iCAP RQ source and interface (blue) with Q-cell technology for suppression of matrix ions
  • The TOF ion drift chamber (yellow) of the icpTOF 2R is two times longer than that of the icpTOF, leading to a doubling of mass resolving power
