The SCIEX Echo® MS system, when paired with the SCIEX Triple Quad™ 6500 or 6500+ mass spectrometer, represents a shift in how laboratories approach high-throughput mass spectrometry. By combining acoustic droplet ejection with triple quadrupole mass spectrometry, this setup enables rapid, LC-free analysis for screening-based workflows.
As interest grows in high-throughput mass spectrometry, acoustic ejection MS, and LC-free MS workflows, the Echo MS and Triple Quad 6500 pairing has become a frequently researched configuration in pharmaceutical, biotech, and life science environments.
The SCIEX Echo® MS system uses acoustic droplet ejection (ADE) technology to transfer nanoliter-scale samples directly from microplates into a mass spectrometer. This approach eliminates physical contact, pipette tips, and traditional liquid chromatography.
Because the Echo MS system does not rely on LC separation, it is often described as LC-free mass spectrometry or chromatography-free MS, making it well suited for rapid screening applications.
The SCIEX Triple Quad™ 6500 and 6500+ are high-performance triple quadrupole mass spectrometers that provide sensitive, reproducible quantitative analysis. When paired with the Echo MS system, they create a streamlined, LC-free workflow that supports high-throughput screening and rapid sample analysis.
This pairing allows laboratories to:
By combining acoustic droplet ejection with the Triple Quad 6500, labs can significantly reduce run times while preserving the accuracy and reproducibility expected from a traditional triple quadrupole mass spectrometer.

Traditional LC-MS workflows can limit throughput due to run times, column maintenance, and solvent use. The Echo MS system paired with the Triple Quad 6500 addresses these limitations by enabling:
As a result, acoustic ejection mass spectrometry is commonly associated with drug discovery screening, compound library analysis, and early-stage research workflows.
The SCIEX Echo MS system with Triple Quad 6500 is primarily used in environments where speed and consistency are more critical than chromatographic separation.
Key applications include:
The system is also referenced in discussions around automation-friendly MS workflows and plate-based mass spectrometry analysis.
