Confocal Micro X-ray Fluorescence 3D Elemental Imaging For Materials Characterization

George J. Havrilla — Fri, 25 May 2012 13:13:03 GMT

Confocal micro X-ray fluorescence is a new instrumental method for materials characterization. In a confocal geometry, the excitation and detection regions are bound by the same foci and therefore, share the same focal spot. This confocal arrangement is achieved by using two monolithic polycapillaries; one focuces the x-rays to a focal spot and the second optic is oriented on the dector side for emission collection from the focal spot. An advantage of the confocal geometry is the capanility o...

Low-mass PM analyzer MEXA-1370PM — Improvement of the Performance for PM Composition Analysis —

Masayoshi Shinohara;Tomoshi Yoshimura — Fri, 25 May 2012 12:23:29 GMT

Particulate matter (PM) emitted from engines is currently measured by the filter weight method. The filter weight method passes diluted emission gases through a filter collecting the PM, and post test weighs the mass of the collected PM on a precision balance. However, this method is time consuming, and with decreasing PM emission volumes, improvements in accuracy were needed. So the MEXA-1370PM was developed, to measure soluble organic fraction (SOF), soot, sulfate and total PM by vaporizing...
