Scope

Main technical content: At present, the main methods used to evaluate heavy metals and harmful elements in food, agricultural products, and traditional Chinese medicines include inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry, and atomic fluorescence spectrometry. However, the determination of heavy metals in Zhi Zhi (Asarum sieboldii) currently relies heavily on atomic absorption spectrometry, but this method is often affected by interference from other elements, which impacts the accuracy of the test results. ICP-MS has the advantages of low detection limits (down to ng/mL or lower), low matrix effects, simple spectral lines, the ability to simultaneously determine multiple elements, a wide dynamic linear range, and the ability to quickly determine isotope ratios. This standard adopts ICP-MS to determine and analyze heavy metals and harmful elements in Zhi Zhi, providing an important reference for the rational development and utilization of Zhi Zhi products and market evaluation.
