What XOS does

XOS is a privately-held manufacturer of X-ray fluorescence (XRF) elemental analyzers and proprietary X-ray optics, founded in 1990 and headquartered in East Greenbush, New York. The company specializes in Monochromatic Wavelength Dispersive XRF (MWDXRF), Energy Dispersive XRF (EDXRF), and Wavelength Dispersive XRF (WDXRF) technologies, supported by its proprietary polycapillary optics and doubly curved crystal (DCC) optics that deliver up to 10,000x flux density gain over conventional pinhole collimators. Its instrument portfolio spans the Sindie sulfur analyzer line (launched 2003), Clora chlorine analyzer line (launched 2011), and Petra multi-element analyzer line, with continuous-process and benchtop variants, plus the fleX-Beam and DCC X-Beam OEM optics modules. End applications include compliance testing of sulfur and chlorine in fuels, marine lubricants, sustainable aviation fuel, biofuels, and plastic pyrolysis feedstocks, as well as research-grade optics sold to academic and government laboratories.

XOS sells through a combination of direct enterprise sales and a global authorized distributor network spanning more than 35 countries across North America, South America, Europe, Asia, the Middle East, Africa, and Oceania, supplemented by a wholly-owned subsidiary in Shenzhen, China opened in 2017. Pricing is quote-based, typically structured as multi-year contracts with associated preventative maintenance, extended warranty, calibration, and consumables (sample cups, films, calibration standards) revenue streams. The company is a subsidiary of Veralto (spun off from Danaher Corporation, which acquired XOS in 2019) and has been featured in a high-profile NASA JPL partnership whose optics flew on the Mars 2020 Perseverance Rover. Key customer verticals are petrochemical refining (primary), biofuels, sustainable aviation fuel, marine, plastic pyrolysis, and research and academic institutions, with named references including ExxonMobil (marine cylinder condition monitoring partnership) and SASH Lubricants. Reported Q3 2025 financials show net income of $2.1 million aided by a $9.4 million one-time lease termination gain against an 8% nine-month revenue decline, with sources flagging ongoing liquidity risk.

The product roadmap centers on the 2026 R Series suite refresh (Sindie R3, Clora R, Clora 2XP R), the Petra SUPRA multi-element analyzer, the Petra Series Autosampler, and the Petra MAX Online continuous process analyzer, indicating a strategy of extending from benchtop lab QC into refinery in-line monitoring while expanding into marine and energy-transition verticals.

Core offering

XOS manufactures mission-critical materials-analysis equipment based on X-ray fluorescence (XRF) technology. The company sells two main product lines: elemental analyzers (Sindie sulfur analyzers, Clora chlorine analyzers, and Petra multi-element analyzers) used for measuring sulfur, chlorine, and metals in petroleum products, biofuels, and other matrices; and X-ray optics (polycapillary optics, doubly curved crystal optics, fleX-Beam, Mini-Beam, and DCC X-Beam) for focusing and manipulating X-ray beams in research and industrial applications.

Product overview

XOS is a provider of elemental analysis and X-ray optics solutions. The product portfolio centers on two main technology areas: (1) Elemental Analyzers including the Sindie, Clora, and Petra product lines for measuring sulfur, chlorine, and metals in petroleum products, biofuels, and industrial samples using XRF technology; and (2) X-ray Optics including Polycapillary Optics, fleX-Beam, DCC Optics, DCC X-Beam, and Mini-Beam for focusing, collimating, and manipulating X-ray beams. The R Series Suite represents the latest generation of benchtop analyzers featuring MWDXRF technology with advanced optics, no consumable gases, and compliance with ASTM D2622, D7039, D7536, and related ISO/GOST standards. XOS also provides Parts and Supplies for maintaining and calibrating instruments. The company was founded in 1990, acquired by Danaher Corporation in 2017, and operates as part of the Veralto company.
