Key benefits of the FAIMS Pro interface
Protect precious samples Fast, higher quality results Low cost and improved ease of operation Focus on science, not setup
The FAIMS Pro technology is the only interface exclusively designed to improve nano, capillary, and microflow applications, allowing you to preserve precious, size-limited samples while achieving higher data quality. The unique design of FAIMS Pro technology enhances instrument selectivity and detection limits using gas phase fractionation. This results in reduced matrix interference and higher quality data, faster. Increased selectivity allows you to improve performance and save time by avoiding or reducing offline sample fractionation preparation steps. No consumable parts means lower long-term cost and maintenance. Designed for inexperienced users to easily install and use. Leverage menu-driven software to design methods using pre-configured parameter recommendations and quickly achieve results.

How does the FAIMS Pro interface work?

The FAIMS Pro interface is easy to set up and deploy to enhance experimental performance and is perfectly suited for nano to micro flow applications (up to 25µL/min). Better selectivity means increased productivity for every proteomic user.

Ion path through the FAIMS Pro interface from emitter tip to MS capillary. Ions introduced into the FAIMS electrodes are only transmitted to the mass spectrometer when the compound-specific compensation voltage (CV) is set. All non-optimized species are filtered out.

Conventional versus differential ion mobility spectrometry (FAIMS)

Identifying and characterizing proteins and post-translational modifications by bottom-up mass spectrometry relies on the acquisition of high quality MS and MS/MS data. The FAIMS Pro interface increases analytical performance through gas phase fractionation and selective enhancement of peptidic compounds, reducing the complexity of the MS spectra, and improving analyte signal/noise ratio. The end result is greater proteome coverage.

Comparison of protein and peptide identifications using conventional setup (no FAIMS) or FAIMS with 3 CVs (-50, -65, and -85 V). The addition of the FAIMS Pro interface enables an improvement of 14% in protein IDs and 19% in peptide IDs when compared to not using FAIMS in DDA mode, with a 90-minute nanoflow gradient on the Orbitrap Fusion Lumos MS.

Free webinar: Enhanced proteome analysis with FAIMS-MS

Michael Westphall HDI

In this session with Dr. Michael Westphall from University of Wisconsin, Madison, learn why ion mobility isn’t what you’ve been missing for high throughput proteomics. When Dr. Westphall connected the FAIMS Pro interface with our LCMS systems it enabled him to obtain up to a 20% or more increase in the number of proteins and peptides detected.
