Bruker Unveils New proteoElute™ nanoLC System and PepSep® Advanced nLC Columns for up to 50% Improved Peptide Sensitivity
- New proteoElute™ nanoflow nLC system features ceramic valves, proteoTrap™ trapping columns, and TwinScape™-enabled predictive maintenance technology
- Introducing new generation of PepSep® Advanced nLC columns to further improve chromatographic resolution, sensitivity and proteomics identifications.
2 June 2025 -- Maryland, US -- At the 73rd Conference on Mass Spectrometry and Allied Topics (ASMS), Bruker Corporation today announced the new proteoElute™ nanoLC system, featuring ceramic valves, proteoTrap™ trapping columns, and next-generation PepSep® Advanced nLC columns, further enhancing robustness, sensitivity and proteome coverage in ultra-sensitive proteomics workflows.
Bruker Introduces the proteoElute™ Next-Generation Nanoflow LC System for Robust, Ultra-Sensitive Proteomics Workflows with Real-time Monitoring
Bruker announces the launch of the proteoElute™, a state-of-the-art nanoflow liquid chromatography (LC) system designed for robust and ultra-sensitive multiomics applications. The proteoElute™ is ideal for single-cell proteomics, immunopeptidomics, microbiome metaproteomics profiling, and many other proteomics methods, ensuring reliable performance even with limited or very complex biological samples.
The proteoElute™ features innovative TwinScape™ technology, which continuously monitors system health in real-time and runs background diagnostics. This proactive approach alerts users to potential issues, providing peace of mind when working with precious samples.
Engineered for relentless reliability, the proteoElute™ includes biocompatible ceramic valves, new porous metal filters, and a proprietary trap column that together enhance robustness, chromatographic performance, and permit sample recovery. The new injector and needle wash system reduces carry-over by up to 3x, a critical advantage for confidently avoiding background signals when analyzing ultra-low input samples.
W. Hayes McDonald, Associate Director in the Department of Biochemistry at Vanderbilt University, commented: "The combination of the new proteoElute UHPLC platform along with updated PepSep Advanced columns and the proteoTrap column allows us the flexibility to perform any state-of-the-art proteomics workflow with highest performance. Its remarkable robustness gives us the confidence to execute all proteomics workflows at scale."
Bruker Introduces PepSep® Advanced Columns for Sharper nLC Peaks, Higher Sensitivity and Further Enhanced Peptide and Protein Identifications
For highest sensitivity and performance of the proteoElute™ nLC system, Bruker introduces a new generation of PepSep® Advanced nLC columns, engineered for precision, robustness, and speed. The columns deliver sharper peaks and higher-resolution separations for even deeper proteome coverage and consistent performance with challenging biological samples. In benchmark studies, the PepSep® Advanced columns demonstrated approximately 20% improvements in peptide IDs and typically 10% improvements in protein IDs.
Combined with CaptiveSpray Ionization (CSI) emitters, users can extend column lifetime by simply replacing the emitter—ensuring long-term performance and cost efficiency. PepSep® columns provide the reliability and depth needed for analyzing complex tissue digests or low-input samples.
Lynn Spruce, the Technical Director at the Children’s Hospital of Philadelphia (CHOP-Penn) Proteomic Core Facility, said: "The new PepSep Advanced columns have proven to be robust, and they consistently deliver reproducible chromatography. They produce sharper, more symmetrical peaks with no observable tailing, resulting typically in 7–8% increases in protein group identifications. Combined with the convenience of interchangeable emitters and reasonable pricing, it has become our go-to nLC column. It’s essentially plug-and-play."
