Mass Spectrometer: 21T FTICR
EMSL’s 21 Tesla Fourier transform ion cyclotron resonance mass spectrometer, or 21T FTICR MS, is one of only two in the world with this high of a magnetic field strength. The 21T FTICR MS significantly enhances EMSL’s overall mass spectrometry analytical and characterization performance in terms of sensitivity, dynamic range, accuracy, resolution and speed.
This unprecedented level of performance is needed to unravel the chemistry and dynamics of complex natural systems in the environment. This transformative instrument enables the characterization of large, intact proteins and complex environmental and biological materials, allowing researchers to tackle previously intractable questions related to microbial communities, biofuel development, climate and environmental remediation.
By greatly advancing the molecular-level understanding of complex systems, this revolutionary mass spectrometry capability will enable better-informed technical and policy decisions affecting environmental remediation, waste processing, energy production and associated impacts to the environment. Moreover, the development of this mass spectrometry capability will ensure that EMSL will continue to provide leading-edge mass spectrometry resources to serve national and international users who are addressing critical Department of Energy mission needs.

In the News
The impressive capabilities and promise of this next-generation instrument was highlighted in a feature article published Sept. 11, 2015, in Science. In the article, Ljiljana Paša-Tolić, EMSL’s lead scientist for mass spectrometry and technical lead for development of the 21T FTICR MS, explained the potential of using this instrument to characterize large, intact proteins in microbial communities or natural organic matter in soils and aerosols. Paša-Tolić was one of six scientists featured in the article.
“Magnetic Attraction,” the cover story in the June issue of The Molecular Bond, EMSL’s bi-monthly newsletter, features the six inaugural studies selected to use the new instrument through a Special Science Call.
