• Description:
  A field portable X-ray fluorescence (FPXRF) analyzer for on site screening and analysis of inorganics in hazardous waste was described. The FPXRF involved a microprocessor controlled analyzer connected to a hand held probe. The probe contained an X-ray source, a detector, and a means of reproducible presentation of the sample for measurement. A sealed radioisotope capsule emitting X- ray or low energy gamma rays was a preferred source of primary radiation for portable instruments. Empirical calibration methods allowed quantitative analysis based on calibration samples. A new Si/Li based hand held probe was developed. The new probe had a 30 square millimeter active area and could be used in any position. The performance of the Si/Li probe was compared with that of a gas filled detector. The Si/Li probe could be used directly with the X- MET-880 in an empirical calibration mode.
