Function and Applications

Upgrade set as an extension of the XR 4.0 X-ray unit.

This set is particularly suitable for the qualitative and quantitative X-ray fluorescence spectroscopy of metallic samples in physics and material science (non-destructive testing).

The set covers the following experiments and topics:

• Various different types of samples can be analysed: powders, solids, and liquids
• Material analyses of pure metals and multi-component alloys
• Moseley's laws energy-dispersive Bragg structure analysis
• Determination of the lattice constant of monocrystals
• Duane-Hunt's law of displacement
• X-ray fluorescence analysis for layer thickness determination
• Characteristics and the special resolving power of an X-ray energy detector

Benefits

• Immediate measurements possible because energy detector does not require warm-up
• Measurement data can be viewed in real-time as soon as x-ray tube is switched on
• In combination with the XR 4.0 X-ray multi-channel analyser, the entire X-ray energy spectrum (2-35 keV) of the analysed materials can be determined.
• The set includes a sensitive XR 4.0 X-ray energy detector with a resolution of FWHM < 400 eV, rate independent up to 20 kcps.
• The XR 4.0 X-ray energy detector is mounted directly and easily onto the XR 4.0 X-ray goniometer (09057-10) of the XR 4.0 X-ray unit.
• Direct connection of the XR 4.0 X-ray energy detector via the internal and external socket panel to the multichannel analyser that also supplies the supply voltage.

Equipment and Technical Data

The set includes the following components:

• XR 4.0 X-ray energy detector
• Multi-channel analyser
• Software for the multi-channel analyser
• XR 4.0 X-ray set of chemicals for edge absorption
• XR 4.0 X-ray lithium fluoride (LiF) monocrystal in a holder
• XR 4.0 X-ray universal crystal holder for the X-ray unit
• XR 4.0 X-ray sample holder for powder samples
• XR 4.0 X-ray diaphragm tube with Zr foil
• additional accessories

Additionally required are an X-ray tube (09057-51, 09057-61, 09057-71, 09057-81) and a goniometer (09057-10).

Include chemicals needed for experiments (09056-04)
