Liquid chromatography-mass spectrometry is commonly used for Met ID but confident soft spot identification is not always possible. Imagine the advantage of unambiguous metabolite identification using liquid chromatography-mass spectrometry (LC-MS) reducing the need for additional safety testing during drug discovery. Quickly and easily generate the information you need using routine assays that are robust and efficient, enabling confident decision-making while also saving time and money. Learn more >
Metabolite identification is a key task during drug discovery to establish safety and efficacy of a drug candidate. LC-MS assays for metabolite identification typically use collision-induced dissociation (CID) to fragment ions for structural elucidation, and soft-spot identification. With challenging metabolites, CID doesn’t produce sufficient fragment ions or help with labile modifications and a clear identification cannot be made. This can lead to the need for additional testing to meet regulatory requirements.
EAD is a fragmentation method available on the ZenoTOF 7600 system that causes ions in an LC-MS/MS experiment to fragment in locations that are different from where they fragment with CID, providing additional information to scientists. For metabolite identification, this could mean confident identification of the metabolite and localization of the site of metabolism, removing the need for additional safety testing.

The Echo® MS+ system is a novel platform for Acoustic Ejection Mass Spectrometry (AEMS) and combines the speed of acoustic sampling with the selectivity of mass spectrometry. This platform has been designed for high throughput analysis of small and large molecules. The technology combines Acoustic Droplet Ejection (ADE), an Open Port Interface (OPI) and could be coupled with the SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system.
The Echo® MS+ system comprises of an open-port interface (OPI) and acoustic droplet ejection (ADE) module which could be coupled with a mass spectrometer. The mass spectrometer could either be a SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system. This non-liquid chromatography based; high-throughput screening platform enables rapid analysis of compounds at speeds of up to 1 sample/second.
The ability to consistently achieve reproducible results on many complex samples across multiple days is critical to a routine clinical laboratory. Laboratories relying on analytical instrumentation require stability and robustness to perform a variety of screening and confirmatory assays with confidence. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has become the preferred analytical method in the clinical laboratory to reliably perform clinical testing as it provides best-in-class performance and reliability for the most challenging assays. LC-MS/MS offers the required levels of sensitivity and specificity for the detection and quantitation of molecules from complex biological samples, helping laboratories deliver highly accurate data for a variety of clinically relevant analytes across a wide range of assays.
