An X-ray fluorescence method for measuring the quantity of test matter removed from carpet by vacuuming and wet extraction in typical carpet cleaning processes is described. In this cleaning effectiveness analytical method, five different test compounds were incorporated into an artificial soil, which was then applied to a test carpet. X-ray fluorescence was used to quantify these elements afte...

this study is aimed to identify sources of particulate matter with mean aerodynamic diameterbelow 10 μm (pm10) present in the atmosphere of the metropolitan area of mexico city (mamc), usingsamples obtained from january 1st to june 30th, 2009, analyzed with x-ray spectrometric techniques.minivol samplers were used to collect samples on polycarbonate filters in three sites (north, center, andsou...

A laser-pump, x-ray probe spectroscopic experiment is described, and the results are shown. The Ga Ka x-ray fluorescence following x-ray absorption, at the Ga K absorption edge was measured, and its increase due to excitation with subpicosecond pulses of laser light at 4.6 eV photon energy was determined. The x-ray absorption, and thus the fluorescence, is increased for about 200 ps after the l...
