How fast is fast?
Cheetahs. Usain Bolt. Tachyons. The Echo® MS system.
They’re all fast. REALLY fast. In fact, they’re the fastest in their categories: the fastest land mammal, the fastest human sprinter, the fastest subatomic particle and the fastest high-throughput mass spectrometry sampling system.
The Echo® MS system sets a new speed record for quantitative mass spec analysis with the ability to analyze up to 3 samples per second. That’s up to 50 times faster than conventional LC-MS. 50 times! But the big difference here is that there is no LC.
Instead, the Echo® MS system uses Acoustic Droplet Ejection (ADE) to basically “vibrate” a nanoliter-sized droplet of sample directly out of the solution from a microwell plate into an Open Port Interface (OPI). Solvents within the OPI sweep the sample directly to the electrospray source of the MS system. Because of the dilution effects that occur within the OPI, matrix suppression effects are essentially eliminated, making for a very clean and sensitive analysis. As a result, most small molecules in drug discovery reach single-digit nanomolar-level sensitivity. And time-consuming sample preparation steps are no longer necessary.
Because there is no LC, contact areas required for conventional LC-MS, such as injection needles and loops, are removed. Sample introduction is achieved through a contactless interaction of the ADE with the OPI. Without these contact areas, carryover from sample to sample is virtually eliminated, even when moving between concentration extremes. Additionally, the lack of LC means the elimination of chromatographic run times as well as LC method development time.
When compared to LC-MS, Chang Liu from SCIEX R&D sums it up nicely:
“The Echo® MS System is much faster, consumes much less sample, requires much less effort for sample preparation or method development and we could eliminate the carryover problems.”1
To increase throughput even more, the hardware and software of the Echo® MS System was designed for easy assimilation into high-throughput environments. Standard robot arms can easily transfer plates to and from the system.
With no sample preparation, no LC method development, no LC run time, incredibly fast sampling and high-throughput design considerations, the Echo® MS System is already changing the field of high-throughput analysis within drug discovery.
Don’t play by the rules. Change the game. And finish your work in record time. To learn more about this game-changing innovation and how you too can “Run Fast,” visit the Echo® MS System website for more information and see how fast is really fast.

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.
