An even more powerful way to cope with spectral overlap is the use of an ICPMS instrument equipped with a double-focusing sector field mass spectrometer (inductively coupled plasma sector field mass spectrometry, ICP-SF-MS) instead of a quadrupole filter. By operating such a mass analyzer at higher mass resolution, the signal of analyte and interfering ions can be resolved in the majority of cases [33,34].

Note Occasionally, the type of mass analyzer is part of the acronym a quadrupole leads to ICP-QMS, a (magnetic) sector field, also termed double-focusing instrument, leads to ICP-SFMS or ICP-DFMS, respectively, and a time-of-flight analyzer to ICP-TOFMS. Again, this is slightly different from the customs in organic and biomedical mass spectrometry where only TOF and FT-ICR tend to be included in the acronym and normally are separated by a hyphen from MS.
