What is Micro-XRF (\u00b5-XRF) ?<\/h4><\/div><\/div><\/div>[vc_column_text css=”.vc_custom_1616437878364{padding-top: 20px !important;}”]X-ray micro-fluorescence (\u03bc-XRF, or micro-XRF) is an analysis technique that conforms to the principles of X-ray fluorescence (XRF)<\/a>. The difference lies in the fact that the \u00b5-XRF have a \u00b5m spatial resolution level, while XRF work at the mm level. A specialized polycapillary optic is used to reduce the X-Ray beam spot size at the \u00b5m order.[\/vc_column_text]<\/div><\/div>[\/vc_column][vc_column width=”1\/2″]
