The Echo® MS system, developed by Sciex, uses Acoustic Ejection Mass Spectrometry (AEMS). This chromatography-free technology generates sample droplets and introduces small reproducible volumes of 2.5nL (scalable to 25nL with multiple injections) to the mass spectrometer via an Open Port Interface with minimal carryover. It not only reduces sample requirements, it also facilitates dramatic increases in throughput with the potential to run 1 second cycle times. Despite these advantages, current potential limitations include reduced sensitivity compared to conventional LC-MS/MS and interference due to lack of separation.
In this poster, we focus on:
- the evaluation of the Echo® MS technology for its application in routine ADME screening
- a comparison of the Echo® MS with established, routine LC-MS/MS methods for the analysis of samples generated from microsomal stability and cytochrome P450 (CYP) inhibition assays
