Whisper 40SpD BETA
This EVOSEP+ method is the ideal choice to achieve robust, very low nanoflow with ultra-sensitive single-cell and phospoproteomics analysis.
SINGLE CELL PROTEOMICS IS A ROBUST STANDARDIZED APPLICATION
Whisper 40SPD beta is the fastest method in a series of methods developed with Whisper Flow Technology. It has a gradient flow of 100 nl/min with a 30 minutes method duration – delivered robustly by standard Evosep One hardware.
The method is ideal for ultra-sensitive applications, such as single cell proteomics, where one of the main challenges is to maintain sensitivity and robustness throughout the workflow.
Ultra sensitive method optimized for single cell analysis
It is part of our dynamic beta environment and updates may be implemented for improved performance.
Webinar: Whisper is here
Learn more about the advantages of the pioneering Whisper™ flow technology in our webinar hosted by Nicolai Bach, Head of Applications at Evosep, from December 16th 2021.
THOUSANDS OF UNINTERRUPTED RUNS WITH THE SAME COLUMN AND EMITTER
This combination is extremely robust as only 20 bars increase in system backpressure was observed after thousands of runs as well as a reproducible flow profile.
IT’S ALL IN THE EVOTIP
The Evotip, a disposable trap column, is the core of our technology. The Evotip serves as an integrated purification step, where contaminants are left on the tip, and analytically relevant peptides are eluted.
This minimizes cross-contamination and extends column lifetime. The Evotip has proven to be extraordinary important for ultra-sensitive analysis, as very small sample amounts can be loaded in higher volumes.
Additionally, loaded Evotips can be stored cold prior to analysis.
Get well started with Whisper
We are proud to introduce our new Whisper methods and would like you to get started well. Here you can find a step-by-step guide describing how to connect your column and emitter to obtain optimal peak shapes and thereby the best chromatographic performance.
Webinar: The launch in 2020
The Whisper™ flow technology was first launched on December 15th 2020. In this webinar, hosted by Nicolai Bache, Head of Applications at Evosep, you can learn more about the principles and advantages of the pioneering Whisper™ flow technology.
Additionally, Andreas-David Brunner from the Mann group at the Max Planck Institute of Biochemistry presents how he has implemented a nearly loss-less sample preparation strategy with the Whisper methods and diaPASEF on the timsTOF SCP mass spectrometer to analyze single-cell proteomics.
