XAN spectrometers for Gold, jewelry and precious metals analysis
The new FISCHERSCOPE X-RAY spectrometers from the proven XAN series are best suited for the gold- and jewelry industry as well as for pawn shops and precious metals recycling. They are optimized for fast, non-destructive analysis of jewelry, precious metals in general, yellow and white gold, platinum and silver, rhodium, coins and all jewelry alloys and coatings.
Measured results are displayed in karat, per mill or weight-%, and easily printed out as customized reports.
They are accurate, safe and easy to use, robust and maintenance free. In addition, they meet the requirements of DIN ISO 3497 and ASTM B 568.
Long-term stability and outstanding precision – better than 1‰ for gold – are benefits of these instruments. In addition, the necessity for re-calibration is significantly reduced thus saving time, effort and cost of ownership.
Excellent ergonomics, easy operation and fast calculation of the measurement best describe the XAN spectrometers. Usage is safe and easy – for experienced staff as well as for employees with little training. There is no need for a special laboratory room.

FISCHERSCOPE X-RAY XDLM and XDAL series
The XDLM spectrometers with micro focus tube and proportional counter tube are ideally suited for the inspection of parts where small structures are measured. Typical applications are measurements on pc-boards, plug contacts and electronic components. XDLM spectrometers are equipped with four exchangeable apertures and a programmable XY(Z) measuring stage. This makes them ideally suited for testing mass-produced parts.
The XDAL spectrometers with silicon PIN detectors provide reliable analysis results and coating thickness readings even with small concentration and very thin coatings. With their fast and highly precise XY(Z) measuring stage, they are ideally suited for automated sample measurements.
The XDAL and XDLM spectrometers have an excellent long-term stability, which is reflected in a significantly reduced calibration effort, among other things.
Using the FISCHER fundamental parameter method, coating systems as well as solid and liquid samples can be analyzed standard-free.

The FISCHERSCOPE®-X-RAY XDV®-SDD is a universally applicable energy dispersive x-ray spectrometer. It is particularly well suited for the non-destructive analysis of very thin coatings, for small concentrations trace analysis and for automated measurements.
Typical areas of application are:
- Analysis of thin or very thin coatings,e.g., gold/palladium coatings of ≤0.1 μm
- Trace analysis on pc boards according to RoHS and WEEE requirements
- Gold and precious metals analysis
- Measurement of functional coatings in the electronics and semiconductor industries
- Determination of complex multi-coating systems
- Automated measurements, e.g., in quality control
To create ideal excitation conditions for every measurement, the XDV-SDD features electrically changeable apertures and primary filters. The modern silicon drift detector achieves high analysis accuracy and good detection sensitivity. Due to large apertures (collimators) and a very fast pulse processor, it is ideally suited for capturing high count rates.
The XDV-SDD x-ray spectrometer has an excellent long-term stability, which is reflected in a significantly reduced calibration effort, among other things. Using the fundamental parameter method, coating systems as well as solid and liquid samples can be analyzed standard-free. It is possible to detect up to 24 elements in a range from aluminum (13) to uranium (92) simultaneously.

Analysis using X-rays
Energy Dispersive X-ray fluorescence spectrometer (EDX) is the instrument to perform qualitative and quantitative element analysis in the range from 6C/11Na to 92U and is the ideal tools for non-destructive applications. EDX is used in many different applications areas in the chemical, electronic and food industries as well as refineries. It can be used with solid, powder and liquid samples. This is achieved by applying X-ray to the sample and then analysing the re-emitted element characteristic fluorescent X-ray. Security functions effectively prevent exposure to X-rays at all times.
Easy handling and improved detection limits
With a simple push of a button, elements ranging from sodium to uranium can be analysed quickly and easily. In addition, the software enables measuring conditions to be adapted to the sample characteristic. For precise analysis of lighter elements the systems can be operated optionally under vacuum or under a helium atmosphere. The built-in five-filter assembly (zirconium, aluminium, titanium, nickel and molybdenum) effectively reduces interferences and increases the signal quality. This way, the limits are markedly improved for detection of e.g. lead, cadmium, chlorine or chromium.
