The ARL X'TRA is a state-of-the-art instrument for powder X-ray diffraction: the new engineering design of the goniometer and Peltier colled Si(Li) solid state detector produce a high performance instrument at an affordable price.
Capabilities include:
– Qualitative and quantitative phase analysis
– Standardless quantitative analysis by Rietveld method
– Crystallographic analysis
– Low and high temperature XRD
The ARL X'TRA XRD system offers the cost-effective solution for high quality powder diffraction applications.
The ARL X'TRA is a new generation of powder diffraction systems from Thermo. Combining 25 years of XRD experience and engineering excellence, the ARL X'TRA offers a cost effective solution for high quality powder diffraction applications in the areas of academic research, chemicals, pharmaceuticals, polymers, semiconductors, thin films, metals and minerals.
Built around a vertical theta-theta goniometer, this instrument offers the most convenient geometry for handling powder samples by facilitating the sample preparation, sample changer options and use of specialized sample holders. In order to optimize experimental conditions, the goniometer features removable dual Soller slits and continuous variable micrometer-controlled slits for adjusting the width of both the incident and diffracted beams. The X-ray optics on the ARL X'TRA goniometer ensures unsurpassed resolution in the low angle region where peaks can be observed down to 0.5°. The system's modular configuration allows the use of various sample stages to fulfill a wide range of different applications.
The ARL X'TRA can also be equipped with Thermo's exclusive Peltier cooled Si(Li) solid-state detector, tuned for high count rate in order to minimize coincidence loss. Thanks to its superior resolution compared to a scintillation detector, it removes K-Beta and fluorescence radiation thus eliminating the need for filters and monochromators. Consequently, the diffraction peak intensities are substantially higher than for other available configurations.
System control for the ARL X'TRA comes from the WinXRD software running under Windows® NT as a true multitasking 32-bit data collection and analysis package.
All in all, the ARL X'TRA represents a substantial advance in both powder XRD technology and system capabilities per investment dollar!
