How REX Works

How REX works.

REX uses patented materials and X-ray fluorescence to capture, measure, and report the dissolved metals in a flowing liquid, automatically, in real time, and without consumables.

How REX captures, measures, and reports dissolved metals.

The process, step by step

Water flows between two plates of our proprietary, patented material, with a voltage placed across them. Ions are attracted to and attach to the appropriate plate depending on their charge. After a set period of time, X-rays fluoresce the collected ions, which are then counted and analyzed by our state-of-the-art detector.

Our proprietary software then sends the results to the email recipients you designate. Every detected element is reported, and any metal that is out of specification is printed in red for easy identification. If process controls are in use, the appropriate actions are completed at the end of the run. Finally, both plates return to their ground state, releasing the collected ions back into the flow stream, preparing REX for its next analysis.

Installation and operation

When your REX arrives, call your sales representative to schedule installation. Your instrument ships from the factory pre-configured to the settings on your purchase order, including the metals to be analyzed, the frequency of analysis, the destination emails, and your process-control parameters.

Your representative unpacks the instrument, inspects it for damage, transports it to the installation site, installs it, and performs an initial run to confirm that every feature works to specification. From there, REX operates under flow conditions at the site of concern with no consumables and no user interface required, performing wellness checks and self-calibrating before each run.

Frequently asked questions

Common questions

How does REX measure dissolved metals?
Water flows between two charged plates of patented material; ions attach by charge, X-rays fluoresce the collected ions, and a detector counts and analyzes them. Results are emailed automatically, with out-of-spec metals flagged in red.
Does REX use consumables?
No. REX operates under flow conditions with no consumables and no user interface, and it self-calibrates before each run.
How are results delivered?
Automatically, by email, to the list of recipients you specify. Out-of-specification metals are highlighted in red.
Who installs REX?
Your sales representative unpacks, inspects, transports, installs, and performs an initial verification run, with your factory-loaded settings already in place.
