Ultra-High Sensitivity for Targeted Mass Spectrometry Applications

The Evosep One is a powerful and standardized platform for LCMS workflows that require a sensitivity boost achieved at low flow rates between 100nl/min to 4ul/min. The robustness and throughput of the standardized methods on the Evosep One combined with the sensitivity of the Agilent 6495C triple quadrupole support targeted analysis of proteomes with ultra-high sensitivity down to the single cell level.

We demonstrated this by targeting selected peptides in a complex background of sub-nanogram material and generated dilution curves spanning several orders of magnitude. To ensure seamless integration of the Evosep One with the Agilent 6495C triple quadrupole, we have developed a native driver for MassHunter and a robust solution for the Agilent nanoflow ion source.


 What you will learn

•    The application of the Evosep One chromatography system to high-throughput analysis of large cohorts.
•    How there is a growing demand for high throughput and standardized workflows to allow  the  analysis of increasingly large cohorts of samples for proteomic research
•    How high sensitivity is achieved for the accurate measurement of low abundant biomarkers
•    How the Evotip was designed to improve efficiency and recovery associated with sample purification and loading ahead of MS analysis.
