What Xoptix does

Xoptix Ltd is a privately-held UK company founded in 2005 and headquartered at Malvern Hills Science Park, Worcestershire. It specialises exclusively in inline process particle size distribution (PSD) measurement using laser diffraction, with direct Fourier optics geometry designed for continuous industrial operation across both wet (slurry) and dry (powder) applications. The core measurement range covers 0.1 to 3600 microns depending on model, with 2000 measurements per second and 16-bit resolution, supporting both Mie and Fraunhofer PSD calculations.

The product portfolio centres on the IntelliSizer family of online particle size analyzers, with specialised variants including IntelliSizer ATEX (certified for hazardous dust environments such as sugar, coal, and biomass) and PharmaSizer (316L stainless steel, hygienic design supporting 21 CFR Part 11 compliance). The RoboSizer provides batch-based multi-spot analysis for grinding circuit monitoring, and the XoptixLAB line extends the platform into laboratory settings with the LT Series laser diffraction instruments, Aerolink and Hydrolink dispersion units, Spraylink, and Nanolink zeta potential instruments. Beyond analyzers, Xoptix delivers complete engineered solutions comprising sampling systems, sample transport, wet dilution (including the patented VSDS), dry dispersion with purge/sheath air windows, modular control boxes, the IntelliSizer software platform with OPC/PLC/DCS integration, and Advanced Process Control (APC) solutions for autonomous grinding circuit optimisation, supported by independent process consultancy services.

The company serves industrial manufacturers across cement and building materials, mining and minerals, metals and metallurgy, carbon and aluminium, pharmaceuticals and food, and chemicals and specialty materials, with named enterprise customers including Sibelco Netherlands, Lunan China United Cement, Huomei Hongjun Aluminum, and Nanjing Nangang Jiahua. Revenue is generated through hardware sales of engineered systems, managed services via APC solutions, professional services through process consultancy, and software subscriptions/updates. Pricing is quote-based with no public disclosure. The go-to-market is direct enterprise sales via industry trade shows (Mining Turkey, Cemtech MEA, AICCE28), technical consultancy-led engagement, and partnerships with process engineering firms. Hundreds of systems are installed globally across Europe, the Middle East, and Asia Pacific.

Broad incumbents

• HORIBA Scientific: Major analytical instrument maker offering the Partica LA- series laser diffraction particle sizers, plus a broad portfolio of spectroscopic and analytical instruments. Competes with Xoptix in lab and inline particle sizing as part of a much wider product range.
• Shimadzu Scientific Instruments: Major analytical instrument manufacturer offering the SALD series of laser diffraction particle size analyzers. Competes with Xoptix in particle sizing as part of a much broader chromatography/spectroscopy/analytical portfolio.
• Malvern Panalytical: Global market leader in laser diffraction particle sizing (Mastersizer lab series, Insitec for inline) and broader materials characterization; owned by Spectris plc. Directly competes with Xoptix in inline PSD via Insitec but operates across a vastly broader portfolio with much larger sales/service infrastructure.

Others

• KIMA Process Control GmbH: German specialist in cement process control, including classifier speed controllers and grinding optimization systems. Xoptix already co-exhibits with KIMA (AICCE28 Dubai 2025); their APC and grinding-control software often integrates with Xoptix's PSD measurement, making them an adjacent technology partner rather than direct competitor.

Direct peers

• Microtrac (Verder Scientific): Direct competitor in laser diffraction particle sizing (Sync, Bluewave, S3500) across both lab and industrial applications; part of Verder Scientific's materials-characterization portfolio. Highly comparable technology stack and target verticals to Xoptix.
• Sympatec: German specialist in laser diffraction and image-analysis particle sizing with strong inline/process offerings (HELOS, MYTOS, TWIN). Closest direct competitor to Xoptix in the dedicated inline PSD niche, particularly in cement, mining, and minerals.
• Fritsch (Verder Scientific): Manufacturer of the ANALYSETTE 22 laser diffraction particle sizer plus wet/dry dispersion units. Direct competitor to Xoptix's XoptixLAB LT Series and dispersion accessories, particularly in lab-quality-control applications.
• Cilas: French specialist in laser diffraction particle size analysis with both laboratory and online product lines. Closely comparable mid-sized specialist competing with Xoptix for the same cement, mineral, and pharmaceutical PSD applications.

Emerging players

• Bettersize Instruments: Chinese specialist in laser diffraction and dynamic image analysis particle sizing (Bettersizer, BeVision). Comparable technology footprint at a lower price point, increasingly competing with Western specialists like Xoptix in cost-sensitive Asian and emerging markets.
• Occhio Instruments: Belgian specialist in image-based and laser diffraction particle size/shape analysis with both lab and industrial offerings. Adjacent competitor to Xoptix, particularly relevant in cement, mineral, and powder-handling applications where Xoptix already has Belgium-based customers.
