A powerful combination: The Zeno trap and electron activated dissociation (EAD) fragmentation Sensitivity is a fundamental performance characteristic of a mass spectrometer. Increasingly higher sensitivities are in constant demand in order to characterize and quantify analytes that are at an ever decreasing abundance.
Electron activated dissociation or EAD is a ground-breaking approach for tandem mass spectrometry applications. While the industry standard collision induced dissociation (CID) has proven to be an invaluable tool for MS/MS experiments, the data produced using CID can leave gaps.
Together the Zeno trap and EAD fragmentation are a powerful combination.
You can now discover new levels of control, with a step change in fragmentation technology. You have the ability to create reproducible fragmentation patterns through high-energy collisions (CID) or, precisely disassemble molecules, exploring new perspectives. You will be able to fine tune fragmentation energies, allowing controlled electron-activated dissociation of all molecule types.
These advanced fragmentation mechanisms create a myriad of insight within your reach. Zeno trap pulsing unlocks extraordinary sensitivity gains, uncovering information that has always existed undetected, adding new perspective to your quantitative and qualitative data.
Together the Zeno trap and EAD provide the ability to acquire key MS/MS features needed to:
The Zeno trap: The next era of sensitivity for accurate mass
Ions are accumulated in the Zeno trap before being pulsed rapidly into the TOF, meaning up to 20x more ions can be detected. Consequently, each TOF experiment contains more useful MS/MS information, particularly on lower abundance species that were previously undetectable, introducing our customers to a new level of sensitivity.
Electron activated dissociation (EAD): A step change in fragmentation technology The ability to tune electron kinetic energy extends the utility of the approach to all molecule types from singly charged small molecules to large multiply charged proteins. EAD allows for a range of reagent free electron-based fragmentation mechanisms within one device, and has the capability to fragment peptides whilst retaining critical MS/MS information for both identification and localization of PTMs. Unlike other electron based fragmentation techniques, EAD delivers reproducible, consistent data, even at fast scan speeds, compatible with UHPLC timeframes, delivering higher efficiency than ETD.
A revolution in accurate mass has arrived. The ZenoTOF 7600 high-resolution accurate mass system combines the power of Zeno trap pulsing with EAD fragmentation which allows for detection of very low abundant diagnostic fragment ion species leading to greater sequence coverage.
Now, you can watch as rare data becomes your everyday and your toughest challenges become your greatest advantage. Now, new discovery is not only possible, but quantifiable.
Welcome to the Zeno revolution.

As therapeutic pipelines continue to diversify, bioanalysis is being asked to do more than ever before. From small molecules to complex biologics, today’s scientists must generate high‑quality, reliable data across a growing range of molecule types and workflows, often under increasing time pressure.
Regulated laboratories are evolving faster than ever. New analytical modalities, higher sample throughput, increasing regulatory scrutiny, and leaner teams are reshaping how work gets done. At the same time, expectations for data integrity, standardization, and operational efficiency continue to increase complexity and/or scope. In this environment, LC-MS software is no longer simply an instrument control platform—it has become a critical part of a laboratory’s quality management system. The question is no longer whether your lab has changed, but whether your software has evolved to support the way regulated labs operate today, and if they are ready and able to meet the demands, they will face tomorrow.
Analyst software has long been a trusted foundation in regulated LC-MS laboratories—and for many, it still performs reliably today. But regulated environments are evolving faster than ever. As labs transition to Windows 11, strengthen cybersecurity policies, modernize IT infrastructure, and prepare for future compliance expectations, software decisions are no longer just about what works today—they’re about managing tomorrow’s risk. Analyst will not be supported on Windows 11. While some labs may continue operating in unsupported environments temporarily, the bigger question is: when that risk becomes reality, will your lab be reacting under pressure—or executing a planned mitigation strategy with confidence?
