Luminol overcoupling indirect determination method is a commonly used chemical analysis method for detecting trace substances in biological samples, such as blood and drugs. This method is based on the chemiluminescence generated by the reaction between luminol and hydrogen peroxide, and calculates the concentration of the target substance in the sample by measuring the luminescence intensity. Due to its advantages such as high sensitivity, good selectivity, and easy operation, the luminol overcoupling indirect determination method has been widely used in biomedical, environmental monitoring, and other fields.

However, there are some controversies regarding the accuracy of the indirect determination method using luminol coupling. On the one hand, this method has high sensitivity and low detection limit, which can detect the presence of trace substances; On the other hand, this method may be influenced by various factors, such as sample matrix, experimental conditions, interfering substances, etc., which can lead to measurement results being biased. Therefore, when using the luminol coupling indirect measurement method, it is necessary to pay attention to the control of experimental conditions and the representativeness of the sample to ensure the accuracy of the measurement results.

In order to explore the accuracy of the indirect determination method of luminol coupling, this paper conducted experimental research. Firstly, we selected various biological samples as the research subjects, including blood, urine, etc. These samples were processed and analyzed using the Lumino coupling indirect measurement method, and the measurement results were recorded. At the same time, we also used other detection methods to compare and analyze these samples, in order to evaluate the accuracy of the luminol overcoupling indirect determination method.

The experimental results indicate that the luminol coupling indirect determination method can accurately detect trace substances in biological samples in most cases. However, in some special cases, such as when the sample contains a large amount of interfering substances or the concentration of the target substance is too high, this method may deviate. In addition, the control of experimental conditions is also an important factor affecting the accuracy of the indirect determination method of luminol overcoupling. Therefore, when using this method, the following points need to be noted:

1. Ensure the representativeness of the sample: When collecting samples, ensure the representativeness of the sample to avoid contamination or cross contamination. For some uneven samples, preprocessing or multi-point sampling is required to improve the accuracy of measurement results.

2. Control experimental conditions: The experimental conditions of the Luminol coupling indirect measurement method have a significant impact on the measurement results, such as temperature, pH value, reaction time, etc. Therefore, these conditions must be strictly controlled during the experimental process to ensure the accuracy of the measurement results.

3. Eliminating the influence of interfering substances: Biological samples may contain various interfering substances, such as pigments, proteins, metal ions, etc. These interfering substances may affect the accuracy of the Luminol overcoupling indirect determination method. Therefore, it is necessary to properly treat and purify the sample before the experiment to eliminate the influence of interfering substances.

4. Comparison with other detection methods: In order to evaluate the accuracy of the Luminol overcoupling indirect detection method, it can be compared and analyzed with other detection methods. For example, for drug residue detection, it can be compared with chromatographic analysis methods; It can better evaluate the accuracy and reliability of the indirect determination method of luminol coupling.

Overall, the Lumino overcoupling indirect determination method is a highly sensitive and easy to operate chemical analysis method. When using this method, attention should be paid to the control of experimental conditions and the representativeness of the sample to obtain accurate measurement results. At the same time, comparing and analyzing with other detection methods is also an important means to evaluate the accuracy of the Luminol overcoupling indirect determination method.
