Abstract
With the development of modern agriculture and animal husbandry, the use of drugs in animal and plant breeding is increasingly widespread, however, the problem of drug residues also comes with it, posing a potential threat to food safety and human health. Therefore, the development of efficient and sensitive drug residue analysis technology is particularly important. High Performance Liquid Chromatography (HPLC), as a mature and widely used separation and analysis technology, has shown excellent performance in the field of drug residue analysis. This article reviewed the research progress, application status and future development trend of high performance liquid chromatography in drug residue analysis. High performance liquid chromatography (HPLC) realizes the separation of substances through the difference of the migration rate of the samples in the liquid phase, and uses the detector to analyze the separated substances quantitatively or qualitatively. The technology has the advantages of high separation efficiency, high selectivity, high sensitivity and fast analysis speed, and has been widely used in food, environment, biology and other fields of drug residue analysis. In drug residue analysis, HPLC can realize the simultaneous detection of many types of drug residues, including antibiotics, hormones, pesticides, etc., providing reliable technical support for food safety monitoring and environmental protection. This paper first introduces the basic principle and instrument composition of HPLC, including the selection and optimization of key components such as column, mobile phase and detector. Then, the specific application of HPLC in drug residue analysis is described in detail, including sample pretreatment method, optimization of chromatographic conditions, establishment of detection method and data analysis. This paper demonstrates the accuracy and reliability of HPLC in the detection of different drug residues, and discusses the challenges and solutions in practical applications. This paper also focuses on the latest research progress of HPLC technology in drug residue analysis, such as multi-dimensional chromatography, ultra-high performance liquid chromatography (UHPLC) and liquid chromatography-mass spectrometry (LC-MS). The introduction of these new techniques further improves the sensitivity and accuracy of drug residue analysis and broadens the application range of HPLC. High performance liquid chromatography (HPLC) plays an important role in drug residue analysis, and its excellent analytical performance provides a strong guarantee for food safety and human health. In the future, with the continuous progress and innovation of technology, HPLC will have a broader application prospect in the field of drug residue analysis.
