Portable Field Desktop Test Stand (FDTS) for Niton XL2 & XL3t Handheld XRF Analyzers

The Field Desktop Test Stand (FDTS) is a portable accessory designed for use with Thermo Scientific Niton XL2 and Niton XL3t handheld XRF analyzers. This collapsible stand converts a handheld XRF analyzer into a stable, closed-beam testing workstation for analyzing small samples, powders, soils, liquids, and other materials that are difficult to test in handheld mode.

By securely mounting the analyzer into the stand, the FDTS allows operators to perform safe, controlled, repeatable XRF measurements while fully containing the X-rays emitted by the instrument during testing.

The FDTS is designed specifically for field portability. The stand folds down and stores inside the included carrying case, allowing users to easily transport the system between job sites, laboratories, and field testing locations.

This accessory is widely used by professionals performing environmental soil analysis, mining exploration, powder metallurgy testing, precious metal analysis, and laboratory sample preparation for handheld XRF instruments.

The sample chamber is approximately 8.75x6.25x4"

Closed-Beam XRF Testing for Safe Operation

The Field Desktop Test Stand allows compatible Niton analyzers to operate in a closed-beam configuration, fully containing the primary X-rays emitted during testing. This design improves operator safety when analyzing prepared samples and helps create a controlled testing environment for handheld XRF analysis.

Closed-beam operation is particularly useful when testing powders, soils, liquids, or small parts that require longer analytical measurements.

Field Portability

The FDTS is designed specifically for portable field deployment. The stand collapses into a compact configuration and stores inside the included carrying case, making it easy to transport between:

• Mining exploration sites
• Environmental testing locations
• Scrap metal facilities
• Mobile laboratories
• Temporary field sampling stations

This allows operators to perform laboratory-style XRF analysis in field environments.

Improved Sample Repeatability

By securely holding the analyzer in a fixed position, the test stand significantly improves sample measurement repeatability compared to handheld testing.

A stable testing geometry ensures consistent positioning between the analyzer and sample, which is particularly important when analyzing:

• Powder samples
• Crushed rock or soil
• Small metal pieces
• Prepared sample cups
• Liquids or slurries

Improved repeatability helps produce more consistent and reliable elemental analysis results.

Ideal for Difficult Sample Types

The FDTS expands the capabilities of handheld XRF analyzers by enabling analysis of samples that are difficult or impractical to test in handheld mode.

Common examples include:

• Soil and environmental samples
• Powdered materials
• Liquids in sample cups
• Small scrap pieces
• Jewelry and precious metals
• Catalyst powders

Fast Analyzer Mounting

The handheld XRF analyzer clips securely into a connector located on the base of the FDTS, allowing fast installation or removal of the instrument.

Remote Operation from a Computer

When connected to a PC, the analyzer can be remotely operated to perform tests and manage analytical data. Operators can:

• Start and stop measurements
• Adjust analytical settings
• Download stored results
• Manage test data

This enables bench-top style workflows using a handheld XRF analyzer.

Typical applications include:

• Environmental soil analysis
• Mining and mineral exploration
• Powder metallurgy and chemical analysis
• Jewelry and precious metal testing
• Catalyst and powder testing
• Scrap metal sampling of small parts
• Laboratory-style analysis using handheld XRF

Frequently Asked Questions

What is a handheld XRF test stand?

A handheld XRF test stand is an accessory that holds a portable XRF analyzer in a fixed position so that samples can be analyzed safely and consistently. Test stands allow operators to analyze powders, soils, liquids, and small items that cannot easily be tested in handheld mode.

Does the FDTS contain the X-rays from the analyzer?

Yes. The Field Desktop Test Stand is designed to fully contain the X-rays emitted by compatible Niton analyzers when used correctly, enabling safe closed-beam operation.

Why use a test stand with handheld XRF?

Using a stand allows operators to:

• Improve measurement repeatability
• Analyze small or irregular samples
• Run longer tests for better detection limits
• Perform laboratory-style testing in field environments

Can the analyzer be controlled remotely?

Yes. When connected to a computer with a USB cable, the analyzer can be remotely controlled to run tests and download analytical results.
