Mobilion Systems Unveils Novel High Resolution Mass Spectrometry Functionality Representing A Paradigm Shift In Speed And Sensitivity For Proteomics Workflows

(MENAFN- PR Newswire) Groundbreaking new approach achieves unparalleled throughput while dramatically increasing sensitivity and accuracy for mass spectrometry applications in proteomics and beyond

CHADDS FORD, Pa., Oct. 21, 2024 /PRNewswire/ -- MOBILion Systems, Inc. , a leader in separation science innovation, today announced a next-generation approach for complex sample analysis poised to disrupt the mass spectrometry industry as it delivers unparalleled speed, sensitivity, specificity and quantitative accuracy for proteomics, lipidomics and metabolomics workflows. In a comprehensive white paper titled "Abandoning the Quadrupole for Mass Spectrometry Fragmentation Analysis ," MOBILion reveals how harnessing the game-changing capabilities of its proprietary structures for lossless ion manipulation (SLIM)-based high-resolution ion mobility (HRIM) technology enables fragmentation analysis at unprecedented speeds, increasing throughput five-fold, detecting low-abundance signals with near 100% ion utilization efficiency, and providing unmatched precision in the identification of complex biomolecules.

"This is a pivotal development for MOBILion that we have been building toward since MOBILion's inception. Replacing slow, inefficient, lossy quadrupole isolation with high-resolution mobility separation provides unmatched speed and peak capacity and represents a paradigm shift in mass spectrometry, one that will redefine the industry for decades to come and open doors to untold scientific discoveries across countless disciplines," said Melissa Sherman, Ph.D., CEO of MOBILion Systems. "Initially targeting the field of proteomics, our new approach aims to deliver faster methods and greater coverage, achieving speed, specificity, and sensitivity without compromise."

Daniel DeBord, Ph.D., Chief Technology Officer at MOBILion and lead author of the white paper said: "For over twenty years, instrument developers have been trying to find a way to overcome the duty cycle and sensitivity limitations imposed by traditional tandem high resolution mass spectrometry (MS/HRMS) approaches, which use a quadrupole filter that can only analyze one or a few analytes at a time and discards the rest. MOBILion's new approach called Parallel Accumulation with Mobility Aligned Fragmentation (PAMAF) removes the inherently slow and inefficient quadrupole from the workflow and replaces it with a HRIM separation, resulting in fragmentation data with ten times higher signal to noise at a speed five times faster than any other incumbent system. I am particularly excited to see the impact this development will have in multiomics applications, where faster and more sensitive MS/MS has shown a clear correlation with the range and number of compounds that can be detected. It has the potential to address some of the biggest challenges in drug discovery and disease research. As we note in the white paper , for personalized medicine approaches, this has the potential to be the difference between a dream and a diagnostic breakthrough by enabling scientists to successfully identify more proteins, lipids, metabolites, and other analytes from complex samples at lower concentrations in a shorter period of time."

Unlike traditional MS/MS that trades the number of target analytes with the sensitivity of analysis, PAMAF enables simultaneous processing of all precursors without sacrificing sensitivity inherent to traditional quadrupole isolation. Additionally, by eliminating the traditional quadrupole filter, PAMAF enables the following over conventional approaches:
