A PIXE analysis method for simultaneous multi-element analysis of atmospheric particles was designed for collecting NIST urban particulate matter (SRM 1648) with Pd-carbon powder mixed in a quartz fiber filter (Pallflex Fiber Filter, Model 2500 QAST, 47 mmφ) in one of two ways under dry or wet condition, and investigated detachment of the collected samples from the filter and accuracy of PIXE analysis.
Almost complete detachment of the collected samples from the filter was achieved by means of a nitric acid-microwave oven method using a simple small container. Elemental determined values by the proposed method were almost completely consistent with NIST certified and non-certified values.
