The CheMin XRD/XRF, which has been proposed for robotic spacecraft missions to Venus, the Earth's moon, Mars, Europa, and a comet nucleus, is a compact instrument with no moving parts that performs simultaneous XRD and XRF. CheMin utilizes a highly collimated miniature low-power X-ray source, a transmission sample geometry and a two-
offers the unique capability of simultaneous XRD and XRF characterization with a single detector in a package expected to weigh under 1 kg with a volume smaller than 1 liter. Prototype instruments built at NASA-ARC have demonstrated the capabilities of the CheMin concept [2,3].
(XRD/XRF) instrument has been evaluated with silica, carbonate, and sulfate minerals and with a basalt, to examine the capabilities of this tool in mineralogic and petrologic exploration for exo- biological goals. This instrument, CHEMIN (chemical and mineralogical analyzer), is based on an innovative low-power X ray tube, transmission geometry, and CCD collection and discrimina-

With up to 28 elements measured simultaneously in concentration ranges from ppm to , the Malvern Panalytical Axios FAST simultaneous WDXRF spectrometer is the ideal solution. Accurate and robust analysis, ease of operation by less-experienced staff and high uptime go .
The X-rays source is a copper anode tube, with a maximum 40Wpower:40 kV,1 mA. A collimating polycapillary system gives a quasi parallel outgoing beam with a very low divergence. The diameter of the beam is about 4 mm. The XRF signal is collected with a SDD X fluorescence detector with a resolution less than 140 eV at 5.9 keV.
An iron-based catalyst with excellent performance and low price was used for simultaneous removal of SO2 and NOx in a typical Fenton system. The catalyst was developed from fly ash of pulverized coal furnace by alkali-magnetic modification process. In other words, the raw fly ash was first modified by Ca(OH)2, which destroyed the vitreous shell and made the internal substances such as Al2O3 ...
The legacy of planetary X-ray Diffraction (XRD) and X-ray Fluorescence (XRF) began in 1960 when W. Parish proposed an XRD instrument for deployment on the moon. The instrument was built and flight qualified, but the Lunar XRD program was cancelled shortly before the first human landing in 1969.
