Unlock the Future of Lithium Mining with Tveskaeg® NMR Lithium Analyser

Get the Most Out of Every Drop

Tveskaeg® NMR measures lithium directly in your brine, so you can act on real numbers while the process is running. Faster decisions mean less downtime, tighter recovery and more value from every drop, without reagents, dilution or lab turnaround.

Factory Calibrated for Your Needs

With NanoNord’s Tveskaeg NMR Technology, your business can rely on factory-calibrated sensors tailored to your specific needs when measuring various isotopes: lithium, sodium, chloride, boron, and bromide. All Tveskaeg NMR sensors are delivered pre-calibrated to ensure precise and accurate measurements.

The Gold Standard of Lithium Analysis

Choose Tveskaeg NMR for top-tier lithium analysis, backed by extensive research and real-world expertise.

In a world driven by the power of lithium, precision is paramount. Whether in battery production, mining, or nuclear energy, Tveskaeg NMR technology is the pinnacle of reliability, efficiency, and accuracy. The technology eliminates guesswork, delivering lithium measurements with a standard deviation of ±2% in about two minutes, with no saturation limit.

The Tveskaeg® Advantage

Get ahead in the lithium market with Tveskaeg NMR, your ultimate solution for precise and efficient lithium analysis. Experience accuracy, efficiency, and simplicity like never before.

Quick Results

Real-time data on your lithium content, so you can make decisions immediately, less downtime, lower cost, higher throughput.

High Accuracy

±2% standard deviation, repeatable measurement after measurement, precision you can run a process on.

Easy to Use

Factory-calibrated and built for the end user. Minimal training, no specialist required.

Multiple Isotopes

Measure lithium, sodium, chloride, boron and bromide on one platform, in a single task.

No Chemicals

Unlike ICP, there are no reagents or added chemicals, safe, simple and nothing hazardous to dispose of

Auto Compensation

Tveskaeg NMR technology auto-compensates for all matrix effects, requiring no re-calibration when swapping sample types.

Industrialised NMR Technology for Lithium Operations

Conventional lab methods, such as ICP-OES, ICP-MS and AAS, can't measure in situ or in real time. They rely on grab samples sent to a lab, creating a control lag of hours to days, so decisions are always made on old data.

Tveskaeg® NMR is built for the process itself: an industrial, in-line analyser that reads lithium and other relevant isotopes directly in the stream, in about two minutes, with stable calibration even in high-sodium brine. That closes the lag and puts process control back in real time.

“There is only one good realtime lithium sensor.” 
Andrew Walker - CMO of Evove

WHY NOT ICP?

How Tveskaeg® Compares

Every established method for lithium in brine is laboratory-based. They are accurate, but they cannot measure in your process in real time.

From Brine To Decision

How It Works

Four steps, no laboratory in the loop.

STEP 01

Connect On-Line

Tap into your brine stream, or run the same unit at-line or offline. Handles pumpable liquid up to 5 bar and 90 °C.

STEP 02

Measure Directly

NMR reads lithium and other relevant isotopes in the sample itself, no reagents and no acid digestion.

STEP 03

Stream The Data

Results pass to your control system over Modbus*, with Wi-Fi and remote monitoring available by region.

STEP 04

Act In Real Time

Adjust recovery while the process is still running, instead of waiting on a lab report tomorrow.

QUESTIONS

Frequently Asked Questions

The things experts ask us most about.

What does Tveskaeg® do?

Tveskaeg uses NMR (Nuclear Magnetic Resonance) technology, where strong permanent magnets create a magnetic field that interacts with atomic nuclei in the sample. By measuring their response, the system can determine composition-related parameters without destroying the sample.

Tveskaeg brings this measurement principle into industrial production, providing near real-time sensing and monitoring that gives operators continuous insight into product quality and process performance.

What can Tveskaeg® measure?

Depending on the application, Tveskaeg can quantify elements such as Li, Na, Cl, Fl, P, N, B, Br and more.

What skill level is required to operate the system?

Tveskaeg® analyzers are designed for use in industrial production environments and do not require operators to be measurement specialists. With minimal training, production and quality personnel can perform routine operation.

Can Tveskaeg® measurements be used directly in production?

Yes. Tveskaeg systems are designed for industrial environments and can support online or at-line quality monitoring, helping operators make faster process decisions without relying solely on traditional laboratory testing.

How can Tveskaeg® help improve production?

Real-time measurement gives QA and R&D teams better visibility into their process. This can help improve consistency, identify deviations earlier, optimize dosing and processing conditions, and provide useful data for quality documentation.

Does the Tveskaeg® system require calibration?

No post-factory calibration is required. Tveskaeg systems are factory calibrated and designed to maintain measurement performance without routine on-site recalibration, reducing maintenance requirements, operator involvement, and production downtime.

How do I know if Tveskaeg® is suitable for my application?

The best starting point is to discuss your process, what you need to measure, the expected measurement range, and where the measurement should take place. From there, we can recommend the most suitable Tveskaeg solution for your application.
