Application Preface

 Citrus leaf quality control samples are widely used in laboratories across various industries as an important quality control tool and serve as a standard for evaluating the analytical capabilities of laboratory instruments and personnel. The significant value of the citrus leaf quality control sample GBW10020 is reflected in the following aspects:  Environmental Quality Assessment As part of plants, citrus leaves absorb trace elements that can reflect the conditions of the surrounding environment. For example, the detection of high levels of heavy metals such as lead and cadmium in citrus leaves may indicate soil or air pollution. Pollution Source Tracing By analyzing the types and contents of different trace elements in citrus leaves, the sources of pollution can be inferred. For instance, certain industrial activities emit specific heavy metals, and abnormal levels of these elements in citrus leaves can help locate pollution sources.  Soil Fertility Evaluation Trace elements in citrus leaves such as zinc and iron are essential nutrients for plant growth, and their contents can reflect soil fertility. If the levels of these elements are low, it indicates a lack of corresponding nutrients in the soil, requiring supplementation through fertilization. Plant Health Monitoring Trace elements participate in various physiological processes in plants, such as enzyme activity regulation and protein synthesis. The balance of trace elements in citrus leaves directly affects the health of citrus trees. Analyzing these elements can help identify issues such as plant malnutrition or diseases in a timely manner.

Ensuring Citrus Quality Trace elements in citrus leaves can affect the quality and safety of citrus fruits through metabolic processes in plants. For example, excessive accumulation of heavy metals can lead to a decline in fruit quality and even pose hazards to human health. By monitoring trace elements in citrus leaves, the safety of citrus fruits can be indirectly evaluated to ensure that the citrus consumed by consumers meets food safety standards.  Ecological Research The distribution and content of trace elements in citrus leaves provide data support for studying the interaction between plants and the environment. For instance, researching changes in trace elements in citrus leaves under different ecological environments helps understand the adaptation mechanisms of plants to environmental changes.

 Article Conclusion

 The analysis of 17 elements in citrus leaf quality control samples digested by M6 microwave digestion was carried out using Hansel iQuad 2300 ICP-MS. The results are accurate, and the method is simple and easy to reproduce.

 It is worth noting that when the internal standard recovery rates of Ge and Rh are 80% and 90%, respectively, this method only uses two internal standards (Ge and Rh) to bring the standard values of 17 elements within the certified range. This fully demonstrates the matrix tolerance capability of the iQuad 2300 instrument, which is highly suitable for multi-element quantitative analysis of matrices similar to citrus leaves.

Highlights of the Scheme

Hansel iQuad 2300  The results of the final analysis of GBW10020 (GSB-11) show that all 17 elements can be within the certified value range, and the specific data are shown in Table 2:
