An X-ray fluorescence (XRF) spectrometer is an x-ray instrument used for routine, relatively non-destructive chemical analyses of rocks, minerals, sediments and fluids. It works on wavelength-dispersive spectroscopic principles that are similar to an electron microprobe (EPMA). The relative ease and low cost of sample preparation, and the stability and ease of use of x-ray spectrometers make this one of the most widely used methods for analysis of major and trace elements in rocks, minerals, and sediment.

X-Ray fluorescence is used in a wide range of applications, including:

research in igneous, sedimentary, and metamorphic petrology

soil surveys

mining (e.g., measuring the grade of ore)

cement production

ceramic and glass manufacturing

metallurgy (e.g., quality control)

environmental studies (e.g., analyses of particulate matter on air filters)

petroleum industry (e.g., sulfur content of crude oils and petroleum products)

field analysis in geological and environmental studies (using portable, hand-held XRF spectrometers)

X-ray diffraction (XRD) is a rapid analytical technique most widely used for the identification of unknown crystalline materials (e.g. minerals, inorganic compounds). Determination of unknown solids is critical to studies in geology, environmental science, material science, engineering and biology.


Other applications include:

characterization of crystalline materials

identification of fine-grained minerals such as clays and mixed layer clays that are difficult to determine optically

determination of unit cell dimensions

measurement of sample purity


With specialized techniques, XRD can be used to:

determine crystal structures using Rietveld refinement

determine of modal amounts of minerals (quantitative analysis)

characterize thin films samples

make textural measurements, such as the orientation of grains, in a polycrystalline sample.

Metal Analyzer

Written by

Optical emission spectroscopy using arc and spark excitation (Arc Spark OES) is the preferred method for trace metal analysis to determine the chemical composition of metallic samples.

Optical emission spectrometry involves applying electrical energy in the form of spark generated between an electrode and a metal sample, whereby the vaporized atoms are brought to a high energy state within a so-called “discharge plasma”.

This process is widely used in the metal making industries, including primary producers, foundries, die casters and manufacturing. Due to its rapid analysis time and inherent accuracy, arc spark optical emission spectroscopy systems are most effective in controlling the processing of alloys. Arc spark spectrometers can be used for many aspects of the production cycle including in-coming inspection of materials, metal processing, quality control of semi-finished and finished goods and many other applications where a chemical composition of the metallic material is required.

Gas Purifier

Written by


Rare gases are commonly used to create an inert chemical environment for applications where prohibition of the formation of undesirable molecular species (e.g. oxides, carbides, etc.) in testing is critical, such as Arc/Spark Optical Emission Spectroscopy for metal analysis.


These inert gases are very often stored in compressed or liquefied form in metal containers which are subject to contamination. Gas will then be dispensed through a regulator which is also subject to contamination over time.


This can greatly affect the validity of test results especially where identification of trace elements is required in rigorous applications.

Vacuum Pumps

Written by

vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. Pumps can be broadly categorized according to three techniques:

Positive displacement pumps use a mechanism to repeatedly expand a cavity, allow gases to flow in from the chamber, seal off the cavity, and exhaust it to the atmosphere. Momentum transfer pumps, also called molecular pumps, use high speed jets of dense fluid or high speed rotating blades to knock gas molecules out of the chamber. Entrapment pumps capture gases in a solid or adsorbed state. This includes cryopumpsgetters, andion pumps.

Vacuum pumps are used in many industrial and scientific processes including composite plastic moulding processes, driving some of the flight instruments in older and simpler aircraft without electrical systems, production of most types of electric lampsvacuum tubes, and CRTs where the device is either left evacuated or re-filled with a specific gas or gas mixture, semiconductor processing, electron microscopy, medical processes that require suction, uranium enrichment, medical applications such as radiotherapyradiosurgery and radiopharmacy, analytical instrumentation to analyse gas, liquid, solid, surface and bio materials,mass spectrometers to create a high vacuum between the ion source and the detector, vacuum coating on glass, for durability and for energy saving, such as low-emissivity glass, hard coating for engine components, ophthalmic coating, milking machines, vacuum impregnation of porous products such as wood or electric motor windings, air conditioning service, trash compactor,vacuum engineeringsewage systemsfreeze drying, and fusion research.

Standard Samples

Written by

Certified Reference Material (CRM) is a Reference Material, accompanied by a certificate, one or more of whose property values are certified by a procedure which establishes its traceability to an accurate realization of the unit in which the property values are expressed and for which each certified value is accompanied by an uncertainty at a stated level of confidence.



Reference Material (RM) is a material or substance one or more of whose property values are sufficiently homogeneous and well established to be used for the calibration of an apparatus, the assessment of a measurement method, or for assigning values to materials.



Setting up Samples (SUS) are Samples which have been prepared to meet the daily setting up requirements of laboratories using direct reading spectrometers. Whilst analytical data are supplied with each sample they are not certified as accurate and are not intended to be used as Reference Materials.

Portabl XRF

Written by

Thermo Scientific Niton handheld x-ray fluorescence (XRF) analyzers will

revolutionize your materials analysis, from screening consumer products for

lead (Pb) to testing applications across manufacturing QC, mining exploration

and production, scrap metal recycling, lead paint analysis, and many more uses.

Lightweight and rugged, Thermo Scientific Niton XRF analyzers are purpose-built

to provide elemental analysis in a nondestructive, point-and-shoot operation.

Now you can take measurements anytime, anywhere – for accurate elemental

concentrations available in seconds rather than the hours or days it can take for

a traditional testing laboratory.
