REX

REX: real-time detection of dissolved metals in flowing liquids.

REX (Real-time Elemental X-ray fluorescence) is our flagship product: a fully automated analyzer that detects and monitors dissolved metals in water and other low-viscosity liquids, in real time, down to one part per billion.

What REX does

REX detects dissolved metals in liquid flow systems in real time, down to one part per billion. It is the only product on the market that is fully automated and easy to use, from municipalities to businesses that need to ensure their liquids stay consistent.

Using our patented, highly accurate X-ray fluorescence process-control technology, REX detects and monitors dissolved metals in water and other low-viscosity liquids, such as light oils. It monitors elements from magnesium to uranium, and from high parts per thousand to low parts per billion, completely hands-free.

At a glance

Built for continuous, hands-off monitoring.

Real-time detection, most elements measured to low parts per billion
No consumables
Fully automated and easy to use
ISO 17025 certified to an accuracy level of 99.65% (3 Sigma)
Up to 12 metals at once, where competing technology detects a single metal at a time
Substantial cost savings, conventional labs average about $150 per metal tested

REX vs. the competition

REX can detect up to 12 metals simultaneously, while any competing technology can only detect a single metal at a time. At an average of $150 per metal tested at conventional labs, the cost-savings potential is significant.

Frequently asked questions

Common questions

What metals can REX detect?
REX monitors elements from magnesium to uranium, from high parts per thousand down to low parts per billion.
How many metals can REX measure at once?
Up to 12 at the same time, depending on the X-ray source and filter installed, versus a single metal at a time for competing technologies.
How accurate is REX?
REX is ISO 17025 certified to an accuracy level of 99.65% (3 Sigma).
Does REX need consumables or an operator?
No. REX operates under flow conditions with no consumables and no user interface required; it performs wellness checks and self-calibrates before each run.
What liquids does REX work in?
Water and other low-viscosity liquids, such as light oils.
