X-Ray Fluorescence

A FISCHERSCOPE X-RAY is the ideal choice for non-destructive, contact-free coating thickness measurement and material analysis. Since 1983, our XRF instruments have been an integral part of quality testing in almost all major industries. Our instruments are well-known for their precision, accuracy and durability. At the same time FISCHERSCOPE X-RAYs are designed to be user-friendly and to support you in all aspects of measuring. This enables you to focus on the quality job at hand and not on the measuring instrument.


Is it really gold? Authenticity testing of jewelry and precious metals

Not all that glitters is gold – much less pure gold! If you want to know exactly how much gold it contains, you can rely on our X-ray fluorescence (XRF) measuring instruments: With the GOLDSCOPE SD® you can quickly check the authenticity of jewelry and analyze the composition of gold and precious metals – non-destructively.

The features of the different GOLDSCOPE SD models assist you optimally with your daily work at the jewelry store, the pawnshop or in the testing laboratory. The procedure is clean and requires no chemicals. And like all Fischer X-ray fluorescence XRF spectrometers, the GOLDSCOPE SD measures with the excellent precision you’ve come to expect.

The handling of the XRF devices is tailored to the needs of the precious metals and jewelry industry. The most important measuring tasks for analyzing gold and precious metals are already pre-programmed in the operating software, WinFTM. All you have to do is place the sample on the measurement window and press start. This makes the valuation of jewelry and coins foolproof.

Entry-level X-ray fluorescence XRF analysis

The FISCHERSCOPE® X-RAY XUL® series is truly fundamental equipment for every electroplating shop. These straightforward and affordable energy dispersive X-ray fluorescence XRF analyzers are excellent for monitoring the bath composition, but they’re also indispensable helpers when it comes to quality control: robust and perfectly suited for measuring galvanic coatings on mass-produced parts like nuts and bolts.

All the XRF spectrometers in the XUL / XULM series are easy and intuitive to operate. Larger samples can be simply placed in the measuring chamber by hand; or, for smaller items such as plugs, the instruments can be outfitted with a manual sample stage. Although the measuring devices are compact, they offer plenty of room for your test pieces – up to a height of 17 cm.

And if you have several different measuring tasks, the FISCHERSCOPE X-RAY XULM has exchangeable filters and collimators, so you can create the optimum measuring conditions for all your applications. In addition, the XULM has a built-in microfocus tube, which delivers precise results even with small measuring spots and thin layers.


  • Analysis of galvanic baths and coating thickness measurement with X-ray fluorescence according to DIN ISO 3497 and ASTM B 568
  • Smallest measurement spot with the XULM approx. 0.1 mm; smallest measurement spot with the XUL approx. 0.5 mm

An XRF Instrument for Every Application

Like the XUL series, the XRF instrument spectrometer FISCHERSCOPE® X-RAY XAN® are ideally suited for analyzing simply shaped samples. However, a great advantage of the XAN series lies in their high-quality semiconductor detectors. And X-ray fluorescence (XRF) allows you not only to measure the thickness of coatings but also to analyze the composition of alloys (e. g. copper).

In total, the XAN series comprises 5 bench-top XRF spectrometers that cover a wide range of applications. The XAN 215 has a cost-effective PIN detector. This XRF Instrument It’s is ideal for simple coating thickness tasks, e.g. zinc on iron or Au/Ni/Cu. For more complex applications with alloys or precious metals, we recommend our XRF instruments devices with a silicon drift detector (e.g. the XAN 220): Due to its much higher resolution, it can reliably distinguish between gold and platinum. And when you need to detect traces of heavy metals and other hazardous substances, the XAN 250 is your solution.

Even More Powerful Thanks to DPP+ and Larger SDD

With the XAN 220, XAN 222, XAN 250 and XAN 252, you can now measure even more precisely and quickly. Like the GOLDSCOPE SD 520 and SD 550, the instruments are equipped with the latest digital pulse processor DPP+ – completely developed in-house by Fischer. By using the new processor in conjunction with the also newly available, larger silicon drift detector (50 mm² effective area), even more signals of the sample can be processed. This results in an excellent energy resolution. Your benefit: Shorten the measuring time up to 3 times or reduce the absolute standard deviation of the repeatability by up to 45 %.

The high-end all-rounder

XRF Film Thickness Measurement The XDV®-SDD is one of the most powerful X-ray fluorescence analyzers in the Fischer portfolio for Film Thickness Measurement. This XRF spectrometer is equipped with a particularly sensitive silicon drift detector (SDD). This allows you to measure even the thinnest layers non-destructively – e.g. gold coatings about 2 nm thick on lead frames. 

At the same time, the XDV-SDD is perfectly suited for non-destructive material analysis. For example, its detection sensitivity for traces of lead in plastic is about 2 ppm – several orders of magnitude lower than the values required by RoHS or CPSIA.

So that you can create the ideal conditions for each XRF film thickness measurement, the XDV-SDD has exchangeable collimators and primary filters, which allows work on a scientific level. The extremely robust device is nonetheless easy to operate and is designed specifically for series tests in industrial use. Features like its automatically extending measuring stage and the live image of the measuring site make your day-to-day work easier.
