🚀 Orbitraps on the Move: High-Resolution MS Beyond the Lab! We often hear that Orbitrap mass spectrometers are massive, power-hungry, and permanently stationed in labs—but times have changed! A recent study proves that today’s benchtop Orbitrap Exploris systems can be fully mobile—even operating on battery power while rolling down hospital hallways. Researchers mounted an Orbitrap Exploris on a wheeled cart, complete with a battery-powered UPS, rough pump, and gas cylinder, then moved it through a hospital—including into an elevator—all while collecting stable high-resolution data. Despite movement and acceleration, the instrument maintained mass accuracy within ±5 ppm and stable total ion current, proving that Orbitraps can deliver top-tier performance outside traditional lab spaces. 📄 Check out the full study here: Anal. Chem. 2024, 96, 8234−8242 https://lnkd.in/g4jpTde6 This mobility opens up exciting possibilities for field-based MS, online process monitoring, and real-time chemical analysis. And when combined with Karsa’s MION2—which enables multi-pressure chemical ionization (MPCI)—Orbitraps become even more powerful, offering ultra-sensitive, high-resolution detection of trace compounds in complex environments. Imagine using this setup for industrial process control, environmental monitoring, or even real-time detection of unknown chemicals in dynamic settings. Now, over to you!🫵🏼 🔹 What’s the farthest you’ve shipped or moved an Orbitrap?🛫 🔹 Have you ever used one in an unusual location?🌴🧊🚠 🔹 Any unexpected challenges (or successes) in running an Orbitrap outside the lab?🧪 Drop your stories in the comments! Let’s see where Orbitraps have been on the move! 🚛⚡ (Asked AI to create a picture from the paper—it struggled with the Orbitrap, which we then placed ourselves, but other than that, pretty cute! 😄) #Orbitrap #OrbitrapExploris

🌟 Proud to Power Breakthrough Science in Atmospheric Research! 🌿 We are thrilled to see the role of our MION2 technology highlighted in a groundbreaking Nature Magazine publication that uncovers the connection between isoprene emissions from tropical forests and particle formation in the upper troposphere. Working alongside other advanced mass spectrometry systems, the MION2 of the University of Helsinki helped provide critical molecular-level insights into this complex atmospheric process. This discovery sheds light on the interplay of natural emissions, climate processes, and cloud dynamics, paving the way for more accurate climate models and a deeper understanding of Earth's atmosphere. 🔬 MION2 in Action: A Karsa MION2, operated in bromine ion (Br-) and API mode, played a pivotal role in enabling the detection and quantification of critical atmospheric species, including: * Isoprene-oxygenated organic molecules (IP-OOM): Monomers (C5 species) and dimers (C10 species), essential for nucleation. * Hydroperoxyl radical (HO₂): Key to driving oxidation reactions. * Nitrous acid (HONO): Important for photochemical processes. * Hydrogen peroxide (H₂O₂): A vital oxidizing agent. * Sulfur dioxide (SO₂): A precursor to sulfuric acid. * Sulfuric acid (H₂SO₄): Critical for nucleation, even in trace amounts. * Molecular iodine (I₂): A precursor to iodine oxoacids. * Iodine oxoacids (HIO₂, HIO₃): Stabilizers of molecular clusters. * Methanesulfonic acid (CH₃SO₃H): Contributing to particle growth. * ISOPOOH and IEPOX (C5H10O3): Isomeric oxidation products of isoprene, vital in secondary organic aerosol formation. 💡 Why It Matters: This research provides a critical piece of the puzzle in understanding how natural emissions from tropical forests influence global atmospheric chemistry and climate systems. The findings also emphasize the value of advanced mass spectrometry tools, like the MION2, in driving scientific discovery. 💡 The Future of Atmospheric Research: The study highlights the necessity of using multiple current-generation chemical ionization mass spectrometers (CIMS) to analyze the wide range of volatile organic compounds (VOCs) and highly oxygenated organic molecules (HOMs) involved in particle formation. Addressing this challenge, our newly released Multi-Pressure Chemical Ionization mass spectrometers simplify logistics for field campaigns like CLOUD at CERN by drastically reducing the system footprint while delivering comprehensive coverage with a single instrument. 🌍 Innovation at the Heart of Discovery: We are honored to contribute to the advancement of atmospheric science by equipping researchers with the tools they need to explore the unknown. Together, we are uncovering the mechanisms shaping our climate and inspiring better models for a sustainable future. #MION2 #AtmosphericChemistry #ChemicalIonization #MassSpectrometry #NewParticleFormation https://lnkd.in/dEsXaSUX

🚀 Exciting Breakthrough in Analytical Chemistry & Atmospheric Sciences! 🌍 Introducing a game-changing innovation in gas-phase chemical analysis: Multi-Pressure Chemical Ionization Mass Spectrometry (MPCIMS), as presented in the now peer-reviewed paper "From Hydrocarbons to Highly Functionalized Molecules in a Single Measurement" by Aleksei Shcherbinin, Finkenzeller et al. This groundbreaking method combines high- and low-pressure ionization in a single instrument, enabling the comprehensive analysis of both volatile hydrocarbons and highly functionalized molecules—something that previously required multiple setups. Demonstrated using a-pinene, a critical component in atmospheric chemistry, MPCIMS successfully captures the entire spectrum of oxidation products, paving the way for deeper insights into aerosol formation and air quality dynamics. Key Impacts: + Unified Approach: Eliminates the need for separate instruments for different compound classes. + Enhanced Sensitivity: Leveraging atmospheric pressure chemical ionisation for ultimate sensitivity and low pressure ionisation to capture a broader range of molecules without compromising on detection limits. + Simplified Analysis: Reduces technical complexity and saves space and cost in measurement campaigns.
