| Abstract: | X-ray fluorescence spectrometric method for semi-quantitative analysis microelements in milk power is reported.The average molecular formula is simulated base on the content of major nourishment in milk power.The result shows that the measurement results agree well with standard values by choosing simulative average molecular formula on balance.The benefits of method:sample preparation is simple,analyse elements very quickly,dispense with curve of calibration,precision test by this method is believable. |
