True Mass Presents First Commercial CDMS Instrument To Support Analysis of Macromolecules

TrueMass is presenting the world’s first commercially designed charge detection mass spectrometer (CDMS) at this year’s ASMS in Philadelphia, PA.

Offering the ability to enhance mass spectrometry, widely used in small molecule detection, the TrueMass technology enables detailed analysis of macromolecules such as viruses. For the first time, CDMS overcomes the challenge of identifying the true mass of large biomolecules at high resolution, and at the high throughput needed in today’s research laboratory. By introducing charge as an additional simultaneous measurement to determine the intensity of individual signals, the TrueMass CDMS addresses this long-standing trade-off.

Conventional mass analysers fail to give distinct spectral peaks for large species such as viral capsids and RNA, caused by the continuum of possible charge states delivered by electrospray ionisation and the limitations of charge accuracy. TrueMass overcomes this limitation by measuring both mass-to-charge ratio (m/z) and charge (z) together, resulting in true mass measurements. The CDMS technology incorporates an optimized electrospray source and ion interface, and returns a clear spectral peak for large molecule species in the Mega-Dalton range.

John Hoyes, Founder and CEO of TrueMass, comments: “The pandemic showed us beyond all doubt that we have an urgent need for technology that provides accurate, reliable and in-depth analysis to help us better understand large molecules such as viruses. We have already secured significant investment to enable us to bring the CDMS prototype to proof of concept, testament to its strong potential, advanced analytical capabilities, and the confidence that the investors have in the technology.”

The technology is finding application in biomolecule analysis for investigations into human diseases caused by viruses, such as coronaviruses. Other applications include the analysis of proteoforms, DNA and, in materials technology, the characterization of polymers and nanoparticles.
