Abstract |
A technique is described for making aerosol standards for x-ray fluorescence analysis by depositing sized particles suspended in a carrier solution onto the surface of a polycarbonate filter. Size is controlled by a separate sedimentation step following grinding in a boron carbide mortar and pestle. Binding of the deposition to the filter is accomplished by a collodion film layer applied both before and after the particle deposition. The deposited mass is determined gravimetrically from a companion filter prepared from a large volume aliquot of carrier solution and without collodion. Standards for 18 different elements have been prepared. |
