What is X-Ray Fluorescence?
XRF (X-ray fluorescence) is a non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the chemistry of a sample by measuring the fluorescent (or secondary) X-rays emitted from a sample when it is excited by a primary X-ray source.
Each of the elements present in a sample produces a set of characteristic fluorescent X-rays (“a fingerprint”) that is unique for that specific element.
When the primary x-rays strike the atom, it causes electrons to transfer in and out of their shells, and XRF peaks with varying intensities are created and presented in the spectrum, a graphical representation of X-ray intensity peaks as a function of energy peaks.
The peak energy identifies the element, and the peak height/intensity is indicative of its concentration.
What is LIBS?
LIBS (Laser Induced Breakdown Spectroscopy) is an analytical technique used to determine the elemental composition of materials. A pulsed laser is fired at the sample which then absorbs the energy created. This absorbed energy is rapidly converted into heat which results in vaporization of the sample (ablation) above the surface, that turns into a plasma as heat is increased.
Excited electrons return to ground state in atoms and ions, emitting light which is collected by on-board spectrometers. Apollo software and calibrations compare the wavelengths and intensities of this emitted light to identify and quantify the concentrations of various elements.
The wavelength identifies the element, and the spectral line height/intensity is indicative of its concentration.
Metal & Alloy Analysis
Metal manufacturing and processing has always required monitoring to ensure process accuracy, but with globalized scrap metal trading, the rise in counterfeit metals, and the possibility of inaccurate material test reports (MTRs), all participants in the metal industry—suppliers, distributors, inspectors and industrial consumers—are at risk of alloy mix-ups.
Misidentifying metal hurts your brand and your bottom line. Wrong or out-of-specification alloy grades can lead to potentially catastrophic equipment failures, a well-known issue in the refining and aerospace industries.

Scrap Metal Recycling
The scrap metal recycling industry generates billions in revenue and is projected to keep growing as more and more recycled materials are being used in fabrication processes.
QA/QC in Manufacturing & Fabrication
The potential for material mix-ups and the need for traceability are a concern at every step in the metal fabrication and manufacturing process, from incoming to final product verification.
Positive Material Identification
Thermo Scientific™ Niton™ portable XRF analyzers play an important role in any industry where positive material identification and elemental assays are critical. Niton PMI analyzers are the industry standard.
Precious Metal and Jewelry
Businesses that buy and recycle gold also have a lot at stake. Failing to identify counterfeit gold or inaccurately measuring karat (K) weight of gold jewelry can be an expensive mistake.
Carbon content and mobility are key parameters in many industries such as pipelines, and petroleum refineries. The ability to provide CE values for welding applications in the field saves time and money.
Consumer & Environmental Safety
Toxic metals such as lead, mercury and cadmium potentially touch our lives every day, from paint in homes and buildings to the soil, and in the air to clothing, toys, and electronics.
Thermo Scientific™ Niton™ portable analyzers are trusted by key regulatory agencies to screen consumer products for these hazardous materials. Manufacturers, builders, and remediation specialists rely on our analyzers to positively identify hazardous materials in the field for improved worksite safety and internal quality control.
Protection is in your hands – see how fast and effective hazardous material identification can be.
The identification and remediation of environmental contaminants is a major, costly challenge. The health and safety of your employees is critical, and caution must be taken to identify hazardous instances.
Contaminants in Soils
The use of in-situ analyzers to determine the contaminated hot spots during remediation provides greater accuracy and major cost savings for the project manager. No waiting for lab results to return or paying for disposal of clean soil.
Dust & Air Contaminants
Everyone deserves clean air to breathe, and many industrial sites provide challenges to worker safety. Whether you want to analyze dust samples or to protect workers from airborne exposures, our in-situ analyzers can assist you.
Consumer & Electronic Goods
Testing toys, consumer goods, and packaging for hazardous materials has moved beyond government agencies. Retailers, manufacturers, and importers must all comply with regulations that limit toxic metals.
Mineral Exploration & Processing
From volatile commodities market to financing, safety, and employment issues, the pressure on mining companies to increase efficiency and productivity has never been greater. With a fierce competitive landscape and substantial capital investments at stake, mining companies need to quickly identify and recover the most economically viable resources.
Exploration geochemists seek solutions for rapid sample analysis that will enable them to increase discovery success rates, identify drill targets quickly, make on-site decisions about whether to stop or continue drilling, and decide where to focus on the grid. They must also get an accurate report to the capital markets as fast as possible.
Fast laboratory-grade sample analysis are critical in mineral processing for grade control, trading, and boundary delineation, as well as for quarry operations, upstream oil & gas, and industrial minerals.
With rapid sample analysis, you get real-time assay data to allow operations to make better decisions faster and thus gain a competitive advantage.
Oil & Gas Exploration
Our analyzers are equipped with a fit-for-purpose calibration and operational methodology for light elemental analysis, enabling users to more accurately detect oil-bearing strata, improve mud-logging and support geo-steering. Our analyzers are ideal for light element and trace element analysis required for oil and gas exploration, such as shale gas applications.
Our analyzers provide fast acquisition of geochemical data of elements ranging from Mg(12) to U(92) for early stage exploration, soil surveys and outcrop evaluation. In advanced drilling stages, we identify changing patterns of elements of interest which can help to make “continue” or “stop” drilling decisions, saving time and money.
Achieve the accuracy needed to provide defensible data for process control, quality assurance, and other operational decisions. These include applications such as grade control, delineation of ore and waste boundaries, ore trading, and measurement of heads, tails, and concentrates. Ensure greater accuracy with increased sample preparation, and calibration factors.

Prevent costly radioactive contamination of your scrap yard, steel plant, or your industrial facilities by monitoring incoming material for radioactive isotopes. It is critical that you reject this contamination before acceptance and integration into your current inventory. Eliminate the risk of penalties when you ship contaminated product to your customers. We have various models of differing panel sizes for greater sensitivities.
Zero in on a potential radioactive source quickly and more effectively with a portable handheld device. Once your portable system detects an alarm, quickly isolate and even identify the isotope. Our sensitive radiation meters and spectrometers are easy-to-use, allowing you to reduce the risk to your employees and your business by identifying radioisotope contamination immediately.
Mounting a radiation detection system directly in a grapple allows direct exposure to all the material being handled during pickup, during transportation in the grapple and upon product release. These three scanning conditions allow for the highest degree of detection capability for low level radioactive material. Get closer to the radioactive contamination, scan longer with more accuracy for greater confidence.
