X-ray spectrometer: XRF
|
The Eagle-III µProbe from EDAX signifies a new generation of x-ray microfluorescence (XRMF) spectrometer. Packed into a compact, tabletop design, the Eagle-III is one of the most versatile tools available for elemental analysis.
- Non-destructive sample analysis
- Little or no sample preparation for most materials (solids, liquids, powders, films and coatings, non-conductive, polymers...)
- Large sample chamber accommodates irregular sample sizes and shapes
- Fast, simultaneous, multi-element detection for elements sodium to uranium
- Sensitivity from PPM to 100% concentration levels
- Small analytical spot (down to 40 µm with XPL)
- Analysis in air or vacuum
- Simple, optical based point and click navigation
- Qualitative, quantitative and spatial distribution information
Basic Features
The Eagle uses special capillary optics to focus x-rays onto a sample and can achieve spatial resolution for elemental composition down to tens of microns. As depicted in Figure 1, x-rays are collected at the top end of the capillary and directed by reflection or direct transmission to a focal point several millimeters away from the tip of the capillary. The x-ray fluoresence emitted from the sample as a result of the x-ray excitation is captured by the detector, processed and translated into elemental information which is displayed for the user.
Compared to older aperture-based systems, a capillary delivers more of the tube's x-rays to the analysis area, while providing a greater analytical working distance. This means the user can take advantage of higher x-ray flux to achieve faster analysis times and have the ability to analyze a greater variety of sample shapes and contours.
The basic Eagle components include:
- Micro-focus x-ray tube
- High-efficiency capillary optics for creating small x-ray analysis spot
- Precision, computer-controlled XYZ stage
- Low and high magnification CCD cameras for easy sample positioning and rapid set-up of automated experiments
- Large area Si(Li) detector for enhanced sensitivity
- Large, radiation-safe sample chamber
- Digital signal analyzer electronics
- PC-based software for instrument control and data analysis
