Xevo CDMS
See what no one has seen before
Understanding the mass and heterogeneity of large and complex biomolecules has long been a barrier to advancement. Conventional techniques fail to resolve the information needed to reconstruct the detailed nuance of structure, especially for megadalton molecular assemblies. It can take months or even years of tedious, expensive research to understand the basics of biomolecular structures.
Not anymore. With the breakthrough Xevo CDMS instrument, you can achieve precise measurement of challenging large and highly heterogeneous molecules—including viral vectors, virus-like particles (VLPs), RNA, and protein complexes—that were previously out of reach for mass characterization.
With this incredible innovation in charge detection mass spectrometry (CDMS), your lab can answer questions that were previously unaskable, unlocking the future of biological science, drug development, cell and gene therapy, and precision medicine.

Expand biomolecular analysis beyond traditional tools with CDMS
Traditional characterization methods like SEC-MALS, analytical ultracentrifugation, and mass photometry often fall short for today’s biomolecules. They require large sample volumes, extended run times, or lack specificity. Xevo CDMS overcomes these limitations with direct, single-ion mass measurement across an extraordinary range, from below 1 MDa to beyond 100 MDa, using as little as 10 µL of sample. With streamlined workflows, faster results, and practical precision, Xevo CDMS delivers insights that conventional tools cannot match, making it a powerful complement or alternative in advanced biomolecular research.

Differentiate with direct, single-particle mass clarity
At the heart of Xevo CDMS is the Electrostatic Linear Ion Trap (ELIT), a breakthrough technology that isolates and measures individual ions. By capturing both m/z and charge simultaneously, ELIT calculates the true molecular mass of intact biomolecules with unmatched accuracy. Unlike conventional mass spectrometry, which relies on fragmentation or inference, ELIT preserves macromolecular integrity and provides unambiguous single-particle results. It also determines the exact number of charges for each ion, eliminating the need for assumptions or manual assignments. The outcome is mass clarity for highly complex and heterogeneous assemblies, giving researchers confidence in data that is exact, not assumed.
