Rare Earth Element Analysis Directly in the Field

The Niton XL5 Plus handheld XRF analyzer is purpose-built for advanced geochemical analysis, enabling real-time measurement of rare earth elements (REEs) in complex geological samples.

Rare earth elements—including scandium (Sc), yttrium (Y), and the lanthanide series from lanthanum (La) through lutetium (Lu)—are critical to modern technologies such as permanent magnets, battery alloys, electronics, and renewable energy systems.

The ability to rapidly identify and quantify these elements in the field provides a major advantage in exploration and mining operations.

Built for the Complexity of REE Deposits

Rare earth deposits are not simple. They are mineralogically complex, often spread across multiple phases, and rarely concentrated in a single ore body.

This creates a major challenge:

• REEs occur across multiple minerals
• Each mineral behaves differently during processing
• Economic viability depends on accurate geochemical targeting

The Niton XL5 Plus addresses this by delivering lab-quality elemental analysis directly at the point of sampling, allowing operators to quickly assess deposit viability and target REE-rich zones.

Rare Earth Element Mode for Mining Applications

The dedicated Rare Earth Element Mode on the XL5 Plus is specifically designed for geological analysis, covering a wide elemental range from magnesium (Mg) through uranium (U).

This includes key light rare earth elements:

• Yttrium (Y)
• Lanthanum (La)
• Cerium (Ce)
• Praseodymium (Pr)
• Neodymium (Nd)

In addition, scandium (Sc) and yttrium (Y) are measured to help infer the presence and distribution of heavier rare earth elements within the same deposit.

This gives operators a practical way to:

• Identify REE-bearing mineralization
• Map geochemical anomalies
• Track elemental distribution across a site
• Prioritize drilling targets

Lab-Quality Data Without the Lab Delay

The XL5 Plus has been validated against laboratory methods such as ICP-OES and ICP-MS, showing strong correlation across key rare earth elements including yttrium, lanthanum, cerium, and neodymium.

This means you can:

• Screen samples before sending to the lab
• Reduce lab workload and costs
• Make faster exploration decisions
• Improve drilling efficiency

Out-of-the-box performance is already strong and can be further refined with standardization if required for your operation.

High Sensitivity for REEs and Light Elements

The Niton XL5 Plus delivers the performance required for rare earth exploration through advanced hardware design:

• 5W X-ray tube operating up to 50 kV
• Large-area silicon drift detector (SDD) with graphene window
• Optimized geometry for improved signal collection
• Multiple beam conditions for complex matrices

These features enable high sensitivity across both light and heavy elements, which is essential when working with REEs in challenging geological environments.

Designed for Real Mining Conditions

The XL5 Plus is engineered for field deployment in demanding environments:

• Lightweight and portable for remote exploration
• IP54 rated (dust and splash resistant)
• Integrated GPS for geochemical mapping
• Compatible with external GPS systems for advanced surveys

This allows teams to collect, analyze, and map data in real time across exploration sites and active mining operations.

Sample Types and Preparation

The analyzer is optimized for typical mining workflows, including:

• Drill core and chips
• Soil and sediment samples
• Pulverized rock samples
• Blended exploration materials

For best results, samples are typically prepared to a fine particle size (<250 µm) and analyzed in sample cups using a test stand, ensuring consistent and repeatable measurements.

Accelerate Exploration and Reduce Risk

The Niton XL5 Plus is used to:

• Locate REE anomalies in early-stage exploration
• Identify high-grade enrichment zones
• Guide drilling programs
• Evaluate low-grade ore viability
• Reduce dependence on lab turnaround times

By bringing high-quality geochemical data directly to the field, the XL5 Plus helps mining operations move faster and make better-informed decisions throughout the exploration and production process.

Why Choose a Pre-Owned Niton XL5 Plus?

A pre-owned XL5 Plus gives you access to top-tier rare earth analysis without long lead times.

Ideal for:

• Exploration teams needing immediate deployment
• Mining operations expanding field capabilities
• Consultants supporting REE projects
