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 R and icpTOF 2R Models

The icpTOF R 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 R) to >6000 (icpTOF 2R).  The 2R is 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 R, leading to a doubling of mass resolving power
