How is Olympus XRD different? Small Portable Low unit cost Low power

Conventional XRD Olympus XRD

Low operating cost No moving parts Easy sample prep Fast analysis

Compact Geometry

• Power of x-ray tube can be reduced without sacrificing the number of available photons compared to large instruments

• Lower power tube eliminates need for external cooling and results in overall lower power consumption

r

Debye-Scherrer XRD geometry:Photons fall off as a function of 1/r2

Simultaneous Measurement

• Conventional 2KW instruments take a few seconds to collect each 2Θ measurement and scanning entire 2Θ range can take 15 mins to several hours

• CCD detector used by Olympus collects the entire 2Θ range simultaneously so complete diffraction pattern is visible almost immediately

Simultaneous Measurement

secondary peaks clear

1 min / 4 exposures

3 min / 11 exposures

10 min / 36 exposures

For identifiable peaks, quantification stabilizes

very quickly

secondary peaks visible

primary peaks visible - likely identifiable

Energy Discrimination Detector• Energy sensitive detector distinguishes between

photons with the same energy as the X-ray tube contributing to the XRD pattern vs counts caused by florescence of the sample

• The Smart Sense filter selectively removes the counts caused by florescence to provide better signal-to-noise pattern

Transmission Geometry

• Power of x-ray tube can be reduced without sacrificing number of available photons compared to large instruments

• Lower power tube eliminates need for external cooling and results in overall lower power consumption

• Eliminates need for goniometer and calibrations associated with that equipment used in reflective geometry
