Wave Spectrometer

AZtecWave uses the fully focussing Wave spectrometer with Rowland Circle geometry and curved crystals

• Higher peak to background ratios meaning detection limits lower than 100ppm can be routinely achieved for many elements
• Motorised counter entrance slit optimises resolution and peak to background for every X-ray line
• Optimised for a wider range of energies using higher energy lines for more accurate quantitative results
• • nique dual counters in series using Ar-CH4 for optimised light element and Xe for optimised high energy collection
• Inclined geometry for fast, reproducible and easy sample positioning
• Spectrometer miniview and mimic shows spectrometer position and setup at all times
• Outstanding spectral resolution to fully resolve the most closely spaced X-ray lines meaning the most challenging problems are easily solved

• • SiKa <2eV
  • FeKa <25eV

Rowland Circle Geometry

The Wave spectrometer uses a unique geometry for WDS on the SEM. For this geometry the sample, diffracting crystal and counter must be positioned on the Rowland Circle

• The distance between sample and crystal and counter and crystal must be the same
• Bent and ground crystals are used for best resolution
• No requirement for fragile optic, slow mechanical alignment or transmission losses for higher energy lines
• This unique geometry works at all energies and provides real WDS spectral resolution on the SEM

• Optimised for all energies, meaning the optimum X-ray lines are always available for analysis
• All common overlapping element lines separated including transition metal K lines
• Lowest detection limits, in shorter collection times, with lower beam currents
