Mobile OES – QualiOES™ M

QualiOES™ M is a portable spark optical emission spectrometer (Spark OES) purpose-built for high-speed, on-site metal testing. It bridges the gap between lab-grade accuracy and field practicality, making it the ideal solution for analyzing oversized components or materials that cannot be moved to a traditional laboratory.

The system features a modular design consisting of a portable spectrometer unit and an excitation gun, all mounted on a rugged trolley for easy transport across shop floors or industrial sites.Built on a Paschen–Runge optical platform, it utilizes digital plasma spark technology to ensure consistent, high-precision results.It provides stable, multi-element chemistry verification for a wide range of industrial metals, including:

Carbon and alloy steels
Stainless steels
Aluminum alloys

Mobile OES – QualiOES™ M Application

Incoming material verification and PMI: Mobile OES supports positive material identification when heat numbers, MTRs, or tags cannot be trusted. This helps prevent alloy mix-ups before machining, welding, or heat treatment. It is commonly used for sorting scrap, verifying supplier delveries, and preventing wrong-material incidents.
Weld QA, fabrication, and maintenance inspection: OES enables alloy verification on components already installed or too large to move. That supports on-site inspection of pipelines, structural steel, tanks, and maintenance parts. Results help confirm alloy chemistry before repair or joining steps.
Foundry and metal production control: Production teams can spot-check chemistry and confirm whether material meets target composition. Quick feedback helps reduce rework and supports controlled material flow between stages. It also supports audit-style verification during production changes.
High-altitude and outdoor testing: The system is positioned for field environments where fixed-lab systems are not practical. A ruggedized optical system design and trolley mobility help keep operation stable outside traditional labs. Battery operation supports sites without reliable power access.

Theory and Method

OES works by creating a controlled spark on the metal surface. The spark excites atoms in the sample, producing light at characteristic wavelengths for each element. The optical system disperses that light across a detector, and software converts intensities into concentrations using calibration curves.

QualiOES™ M uses a Paschen–Runge optical structure and a digital spark source with argon flushing for UV lines. This helps measure alloying and residual elements used for grade confirmation and pass/fail sorting.
