With the development of the chemical industry and the development and utilization of natural compounds

,

The earth's environmental pollution is getting worse. According to related news reports

,

The variety identified as environmental pollutants has exceeded

350

Multiple

,

People can find these pollutants in the air, in the soil, in the water, in fish, and in poultry, and some cannot be degraded. At the same time, these pollutants pass through the food chain.

,

They will further contaminate meat, eggs, food, vegetables, fruits and more. The detection of environmental pollution became one of the important research topics in analytical chemistry as early as the beginning of the last century.

High performance liquid chromatography

(HPLC)

It is a new separation and analysis technology developed on the basis of classical liquid chromatography and gas chromatography. It uses a new high-pressure infusion pump, high-sensitivity detector and high-efficiency particle stationary phase and various intelligent software. It has higher efficiency, higher separation speed and faster speed than classical liquid chromatography.

In recent years, high performance liquid chromatography technology has developed rapidly, especially in environmental monitoring. In developed countries, high performance liquid chromatography is a commonly used environmental monitoring method, such as the United States.

Fluorescence analysis of polycyclic aromatic hydrocarbons in solid waste, even the harmful organic compounds in the gas is also determined by high performance liquid chromatography.

High performance liquid chromatography has been widely used in environmental monitoring, especially for the separation and analysis of organic pollutants with large molecular weight, low volatility and poor thermal stability. Such as polycyclic aromatic hydrocarbons, phenols, polycyclic biphenyls, phthalates, benzidines, anionic surfactants, organic pesticides, herbicides and the like.
