| Abstract: | Abstract: Objective Validation and demonstration of mercury analyzer in the determination of total mercury in health foods by direct solid-sampling technique. Methods The levels of total mercury in health foods were measured simultaneously with the mercury analyzer and the atomic fluorescence spectrometry. Results The results of these two methods correlated well. The recoveries ranged from 88% to 116%, with relative standard deviations (RSDs) bellow 10%. Conclusion Mercury analyzer provides an accurate, rapid, low-cost and environment-friendly strategy for analysis of the total mercury in health foods. The results obtained were in good agreement with those from atomic fluorescence spectrometry (the national standard method), making the mercury analyzer an ideal alternative for routine use. |
