Karsa Oy

Thank You for an Incredible Year! 🌟 As the year wraps up, we at Karsa want to take a moment to thank our colleagues, clients, and partners for your trust, support, and collaboration. This year brought valuable opportunities, lessons, and achievements that were only possible through teamwork and shared effort. We are grateful for the conversations at e.g. Slush, #EGU24, #EAC2024, #AAAR2024, #AGU24 conferences, the partnerships with e.g. University of Helsinki, Tampere University, Faculty of Engineering and Natural Sciences (ENS), Cyprus Institute, U.S. Department of Homeland Security, and the milestones we’ve reached together. Looking ahead to 2025, we’re excited for what’s to come—new challenges, fresh ideas, and stronger connections. Together, let’s aim higher, innovate more, and make a lasting impact. We are particularly excited about the transformative impact of our Multi-Pressure Chemical Ionization #MPCI systems using #Orbitrap mass spectrometers, not only in streamlining analytical workflows but also in unlocking immense potential for advancing atmospheric science—ranging from understanding air pollution to exploring climate-critical processes. Wishing everyone a peaceful holiday season and a strong start to 2025! #Gratitude #Teamwork #NewYear #ThankYou #Collaboration #Partnerships #MassSpectrometry #AtmosphericScience 

🚀 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. This innovation not only streamlines analytical workflows but also holds immense potential for advancing atmospheric science, from understanding air pollution to studying climate-relevant processes. 📘 Read the full paper here: https://lnkd.in/dE375sb5 💡 Let’s discuss how this breakthrough could reshape your field or spark interdisciplinary collaborations! #AtmosphericScience #MassSpectrometry #Innovation #EnvironmentalResearch

Topics included the measurement of isoprene and alpha-pinene oxidation products, aromatics, sulfuric acid, synthesized HOM-proxies, nanoparticles, and aerosols.    🌍 The presentations highlighted the diverse applications of MION & Orbitrap across various settings: laboratories, the CERN CLOUD experiment, the SAPHIR chamber, and multiple field campaigns. Field measurements included the Po-valley, pristine high-altitude Izana station in the Canary Islands, Cyprus Observatory, coastal site Tvärminne in Finland, and Hyytiälä.   🙏 We are especially grateful to ACTRIS-RI CiGas and Nina Sarnela for collaborating in organizing this event. And we thank once again all the speakers for sharing their exciting new results: Julia David, Markus Tischberger, Juha Kangasluoma, Avinash Kumar, Jiali Shen, Roseline Thakur, Sana Farhoudian, Mihai Ciobanu, Sebastian Holm, Wei Huang, Runlong Cai and Henning Finkenzeller.   🙌 And finally kudos to all the participants for your interest in the event!

🙌 A big thank you to the Finnish Mass Spectrometry Society (Suomen Massaspektrometrian Seura ry) for organizing such a great event and bringing people together! It was inspiring to learn about the incredible work being done in the field of mass spectrometry across Finland. ⚙️ Our CEO, H.J. (Hans-Juerg) Jost, had the opportunity to present an overview of our technology and share recent results from atmospheric and security applications. Thanks also to everyone who showed interest in visiting our lab. It was definitely a record: our Lab Manager, Joona Mikkilä, did four sessions, spending a total of two hours showcasing our instruments. 👏 #massspectrometry #massspec #chemistry

⚡ Publication alert: A new article featuring MION2 is now out! ⚡   Henning Finkenzeller and co-authors have published a modelling study in Atmospheric Measurement Techniques (AMT) looking at properties of MION2 and Eisele-type inlets. 🙌 We had the pleasure of speaking with Henning about the key results and implications of this research. 📜 Read the full interview on our website (https://lnkd.in/djVvwGEk), and here’s a short part: 𝐖𝐡𝐢𝐜𝐡 𝐩𝐚𝐫𝐚𝐦𝐞𝐭𝐞𝐫𝐬 𝐰𝐞𝐫𝐞 𝐦𝐨𝐝𝐞𝐥𝐞𝐝 𝐢𝐧 𝐭𝐡𝐞 𝐬𝐭𝐮𝐝𝐲? 𝘏𝘦𝘯𝘯𝘪𝘯𝘨: Using the 3D computational fluid dynamics physicochemical model, we looked at some of the key parameters that affect the performance of the inlets: (1) the ion generation from the reagent gas, (2) electro-convective transport of ions to the pinhole, (3) gas flows through the inlet and (4) interactions of gas-phase species with the surfaces. 𝐖𝐡𝐚𝐭 𝐚𝐫𝐞 𝐭𝐡𝐞 𝐩𝐫𝐢𝐦𝐚𝐫𝐲 𝐝𝐢𝐟𝐟𝐞𝐫𝐞𝐧𝐜𝐞𝐬 𝐢𝐧 𝐭𝐡𝐞 𝐩𝐡𝐲𝐬𝐢𝐜𝐚𝐥 𝐪𝐮𝐚𝐧𝐭𝐢𝐭𝐢𝐞𝐬 𝐟𝐨𝐮𝐧𝐝 𝐛𝐞𝐭𝐰𝐞𝐞𝐧 𝐭𝐡𝐞 𝐢𝐧𝐥𝐞𝐭𝐬? 𝘏𝘦𝘯𝘯𝘪𝘯𝘨: The MION2 inlet achieves a near-ideal ion delivery efficiency (or maintains high ion concentrations during transport) to the pinhole due to its efficient charge separation and well-defined electroconvective fields. The Eisele inlet demonstrates lower ion delivery efficiency (10-20%), primarily due to its axis symmetry, which requires diffusion to get ions to the center line and ultimately the mass spectrometer. One big difference is that MION2 selectively introduces the reagent ion only – it keeps the reagent gas separate from the sample gas – while in the Eisele-type inlet the reagent gas is in direct contact with the sample gas, making it prone to contamination. #MassSpec #MassSpectrometry #ChemicalIonisation #Ionsource #MION2
