Kyoto-based Shimadzu Corporation has acquired a 75% stake in Plasmion GmbH, a German deep tech startup headquartered in Augsburg, Bavaria, making Plasmion a subsidiary as of March 23, 2026. The deal, formally announced April 27, gives Shimadzu control of Plasmion's flagship ion source technology, SICRIT (Soft Ionization by Chemical Reaction In Transfer), and positions the instrument maker to deliver prep-free, real-time mass spectrometry capabilities through its next generation of platforms. Plasmion founders Dr. Thomas Wolf (CEO) and Dr. Jan-Christoph Wolf (CTO) will retain the remaining 25% stake and continue in active management roles.
Shimadzu is one of a handful of companies that define the global mass spectrometry market, competing alongside Thermo Fisher Scientific, Agilent Technologies, Waters Corporation, Bruker, and SCIEX. The Kyoto-based instrument maker has consistently expanded its LC-MS portfolio in recent years, with systems targeting pharmaceutical, clinical, and applied markets. Adding SICRIT gives Shimadzu a differentiated ionization capability that none of its major competitors currently offers as an integrated product.
Editor's Note: Sample preparation has long been the silent tax on laboratory productivity in mass spectrometry, consuming time, reagents, and analyst attention before a single ion reaches the detector. The growing field of ambient ionization is changing that calculus, and Shimadzu's acquisition of Plasmion represents a significant commitment to bringing prep-free analysis into a mainstream instrument platform. For lab managers weighing mass spectrometer upgrades or new platform purchases, this deal raises practical questions worth tracking: how quickly will SICRIT-enabled Shimadzu instruments reach market, and will the integration be priced for applied labs or only research environments?
SICRIT technology: overcoming a longstanding bottleneck in mass spectrometry
Sample preparation has historically been one of the most time-consuming and error-prone stages of LC-MS workflows. Conventional ionization sources such as atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI) require analytes to be extracted, cleaned, and often chromatographically separated before they can be reliably detected. A recent editorial overview of mass spectrometry applications from Lab Manager outlines how these workflow demands continue to shape instrument selection decisions in modern laboratories.
SICRIT operates through a fundamentally different mechanism. Using a dielectric barrier discharge to generate a cold plasma at ambient atmospheric pressure, the technology ionizes analytes directly without requiring vacuum conditions, matrix application, surface modification, or extraction. A broad range of sample types, including gases, liquids, and solids, can be introduced and measured in real time.
The module integrates as an add-on connection between existing LC systems and the mass spectrometer inlet. Unlike matrix-assisted laser desorption/ionization (MALDI) or some other ambient ionization approaches, SICRIT requires neither dedicated instruments nor specialized surface preparation. For labs already running LC-MS systems, this means ambient ionization capability could potentially be added incrementally, extending the useful life of existing capital equipment rather than requiring full platform replacement.
Beyond the laboratory bench, the technology's design also enables deployment in industrial and at-line environments. Unlike traditional MS setups typically confined to controlled laboratory conditions, SICRIT can operate in production and process-control settings, offering online quality monitoring without sample removal or offline analysis. This positions the technology as a candidate for inline inspection in pharmaceutical manufacturing, food processing lines, and environmental compliance applications.
Lab Management Certificate
The Lab Management certificate is more than training—it’s a professional advantage.
Gain critical skills and IACET-approved CEUs that make a measurable difference.
A 2025 peer-reviewed annual review of ambient ionization mass spectrometry published in Analytical Science Advances describes the ability to analyze samples in their native state as among the most important recent developments in analytical chemistry, with the field expanding steadily across clinical diagnostics, food science, forensics, and environmental monitoring since the mid-2000s.
Key capabilities SICRIT brings to mass spectrometry users include:
- Direct analysis of solid, liquid, and gaseous samples without extraction, chromatographic separation, or sample pretreatment
- High-sensitivity real-time detection of volatile and semi-volatile analytes that are difficult to capture with standard APCI or ESI sources
- Broad ionization range covering both polar and non-polar compounds, unlike ESI, which is largely restricted to polar analytes
- Plug-and-play compatibility with existing LC-MS platforms, with demonstrated integration on Agilent Ultivo LC/TQ and LC/MSD iQ systems prior to this acquisition
- Non-destructive aroma analysis of food and beverage samples, preserving sample integrity for downstream testing
- Disease biomarker detection through direct breath analysis, eliminating the need for blood or tissue sample collection in early-stage diagnostic research
- Chemical imaging down to 1 µm pixel resolution through laser ablation coupling, without vacuum conditions or dedicated imaging instruments
The table below compares SICRIT against the two dominant ionization techniques currently used in LC-MS workflows:
| Feature | APCI | ESI | SICRIT |
|---|---|---|---|
| Ionization mechanism | Chemical ionization at atmospheric pressure | Electrospray droplet desolvation | Cold plasma via dielectric barrier discharge |
| Sample preparation required | Yes | Yes | No |
| Real-time analysis | Not routinely possible | Not routinely possible | Yes |
| Analyte polarity range | Moderate and non-polar | Polar, high-molecular-weight | Polar to non-polar (broad) |
| Volatile compound detection | Limited | Very limited | Yes, including gases |
| Chromatographic separation required | Typically yes | Typically yes | Optional |
| Instrument integration | Universal | Universal | Modular add-on; growing compatibility |
Seven years of collaboration pave the way for acquisition
Shimadzu and Plasmion have maintained a structured technical collaboration since 2019, sharing proprietary technical information, loaning Shimadzu instruments to the Plasmion team for application development, and co-developing SICRIT workflows for specific use cases. That sustained relationship is the foundation on which the acquisition rests, and it suggests integration timelines may be shorter than those typical of a technology purchase from an unfamiliar vendor.
Plasmion was founded in 2016 and received its first institutional backing in January 2019 from High-Tech Gründerfonds (HTGF), one of Germany's leading deep tech seed investors, alongside Bayerische Beteiligungsgesellschaft (BayBG). The Shimadzu acquisition marks the first time an HTGF portfolio company has been acquired by a Japanese corporation, a milestone the firm cited as evidence of the international market appeal of deep tech originating in Germany. At the time of the deal, Plasmion employed 15 people.
Interested in chemistry and materials science?
In a statement published in the HTGF press release accompanying the acquisition, Dr. Thomas Wolf, CEO of Plasmion, reflected on the startup's journey: "We're very grateful for the continued support received during our journey. It is amazing that we have institutions like HTGF in Germany who are dedicated to identify and support promising deep tech startups with resources, knowledge, and the necessary patience and stamina that is crucial to succeed in these areas."
Before co-founding Plasmion, Dr. Thomas Wolf served as an Engagement Manager at McKinsey & Company and as a research associate at Fraunhofer-Gesellschaft. Dr. Jan-Christoph Wolf brings an analytical chemistry background rooted in a PhD from TU Munich and postdoctoral research at ETH Zurich, where he focused on ionization and fragmentation mechanisms for LC-MS. Their complementary profiles, combining management strategy and deep analytical chemistry expertise, were central to moving SICRIT from academic concept to commercial product in under a decade.
Prior to the Shimadzu deal, Plasmion had established a co-marketing agreement with Agilent Technologies in 2023, enabling SICRIT integration with Agilent's Ultivo LC/TQ and LC/MSD iQ systems. That agreement demonstrated both the technical interoperability of the SICRIT module and the broader cross-platform interest in ambient ionization from established instrument vendors.
What this acquisition means for your mass spectrometry lab
For lab managers running LC-MS workflows in pharmaceutical QC, environmental testing, food safety, or clinical diagnostics, the Shimadzu-Plasmion deal has tangible practical implications. A 2024 Lab Manager survey of mass spectrometry professionals found that greater automation and higher throughput ranked among the most desired developments across the MS community, alongside higher mass resolution. SICRIT addresses both demands directly: eliminating sample preparation accelerates throughput, and direct desorption capability opens analytical approaches that are currently impractical for time-constrained labs.
The integration roadmap is not yet fully published. Shimadzu has confirmed its intention to develop next-generation mass spectrometers by combining SICRIT with its own MS platform technologies, but specific product timelines, pricing structures, or compatibility matrices for existing Shimadzu instruments have not been disclosed. Lab managers evaluating new MS platforms in the near term may want to factor SICRIT integration potential into procurement planning conversations with Shimadzu Scientific Instruments representatives.
The next-generation mass spectrometer market is forecast to grow from roughly $2.1 billion in 2025 to $5.1 billion by 2035, a compound annual growth rate of approximately 9.6%, driven by demand for greater sensitivity, automation, and analytical versatility. As one of the world's largest analytical instrument manufacturers commits to building ambient ionization into its product roadmap, SICRIT is likely to reach a far wider range of laboratory environments than a 15-person startup working through partner agreements could achieve alone.
