Determination of F and Fe elements in the non-stick pan inner coating
The mapping of elements in the non-stick pan inner coating were analyzed using scanning electron microscope(SEM)and energy dispersive spectrometer(EDS)under acceleration voltage of 10 kV.The results showed that the over-lapping between the K spectrum series of F element and L spectrum series of Fe occurred led to.the difficulty to distinguish F and Fe elements in the mapping.By changing the spectrum series of Fe from L to K or employing the TruMap function of EDS software,the true distribution of Fe element could be obtained.By combining the point spectrum fitting with quantita-tive analysis results,the true position of F element in the mapping was determined.
