The ARL 9900 OASIS X-ray spectrometers provide high sensitivity of analysis thanks to optimized X-ray optical design. Mid power negates the need for external water cooling. Configurations are based on various analytical modules such as: •Fixed channels for fast elemental XRF analysis •Gearless goniometer for flexibility in elemental XRF analysis •Integrated XRD system allowing phase analysis for process control applications •12-98 position sample changers
