AB  - A novel method for the analysis of ZrO2 powder via in-situ separation of the 
      matrix from the analytes is described, based on the use of a 
      polytetrafluorethylene (PTFE) emulsion as a chemical modifier. The main affecting 
      factors, including the flow rate of carrier gas and auxiliary carrier gas, ashing 
      temperature and time, matrix concentration, signal record time, and vaporization 
      temperature and time, were investigated systematically. Under the optimum 
      operating conditions, the detection limits (DL) of analytes vary from 4.2 ng x 
      mL(-1) (Al) to 11 ng x mL(-1)(Fe). The relative standard deviations (RSDs) are 
      3.1%-4.9%.
