X-ray Analytical Microscope
The XGT-7200 represents a completely new generation of XRF microscope, and leads the way to a new era of science. It offers a seamless merger between optical observation and elemental analysis functions, revolutionizing the world of micro-analysis and establishing micro-XRF as a routine tool for the research and analytical scientist.
Unique hardware features ensure the system offers versatility and flexibility for every measurement. A choice of two software controlled x-ray guide tubes with diameters ranging from a unique 10 µm through to 1.2 mm allow conditions to be optimised for a range of measurements, including both micro and macro. Similarly, with the unique Dual Vacuum Modes it is possible to switch within seconds between a high sensitivity full vacuum mode and a versatile localised vacuum mode. The latter maintains samples at atmospheric pressure whilst retaining sensitivity to all elements from sodium to uranium.
In any configuration the intelligent combination of optical cameras ensure that the precise analysis position can be quickly and simply located.
Quickly proceed from a view of the entire sample to the selection of the analysis potision.
Intuitive "click and move" images from low magnification and high magnification cameras within the sample chamber, allow the analysis position or mapping area to be defined withing seconds.
Single Point and Multi-point Analysis
Single point and automated multi-point analyses allow high quality spectra to be acquired from either a single position, or from a number of user defined points across the sample. Element peaks are automatically located and labelled, and quantitative analysis down to ppm levels can be carried out using the fundamental parameters method (FPM), FPM with single standard, and full standard sample calibration.Thickness calculations can also be made on nm and µm thick multi-layered structures.
Hyperspectral Mapping Analysis
The SmartMap imaging software records a full EDXRF spectrum at each and every pixel of the element image, enabling post-acquisition element image generation and comparison, and spectrum generation from user defined regions in the image with subsequent qualitative and quantitative characterisation.
Transmitted X-ray imaging provides additional insight into a sample’s structure, allowing features invisible by eye to become immediately apparent.
Element image display
Element images to be displayed can be selected during and after acquisition. Images can aslo be generated from user defined spectral windows.
RGB Composite Image Generation
Overlay elemental images to allow easy comparison of element distribution
Generate the average spectrum from a user defined region within an image.
Display multiple element intensity profiles across a defined region of an image.
Element images can be exported in data or image formats. The entire hyperspectral datacube can be exported in RAW format.
The unique features of the XGT-7200 have seen this innovative micro-XRF analyser widely embraced for a range of applications, including electronics, engine wear analysis, forensic science, geology, mineralogy, pharmaceutics, museums, metallurgy, biology, medicine and archaeology.
The flexible XGT-7200 micro-XRF system covers everything from macro analysis, for a general survey of a wide area, to the inspection of a specific micro area, with simultaneous XRF and transmission imaging. Its many features ensure high performance analysis with easy operation.
