As an important raw material for organic synthesis, diethylene glycol butyl ether has a wide range of applications in chemical industry, medicine and other fields. In the process of production and use, there may be some quality and safety risks. Therefore, it is very important to establish effective detection methods and analysis techniques. In recent years, with the continuous development of science and technology, the detection method of diethylene glycol butyl ether is constantly improving and innovating.

One of the common detection methods of diethylene glycol butyl ether is gas chromatography-mass spectrometry (GC-MS). The technology has the advantages of high sensitivity and good resolution by volatilizing diethylene glycol butyl ether in the sample into a gaseous state, and then separating it through a gas chromatographic column, and finally detecting and qualitatively analyzing it through a mass spectrometer. This method has been widely used in the detection of food, cosmetics and other fields, and provides reliable technical support for ensuring product quality.

Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is also one of the commonly used methods for the detection of diethylene glycol butyl ether. This technology uses the separation and purification of diethylene glycol butyl ether in the sample in the liquid phase, and then detects and quantitatively analyzes it by a mass spectrometer. It has the characteristics of high sensitivity and good selectivity. In the fields of medicine and environmental monitoring, LC-MS/MS technology is widely used in the residue detection and environmental monitoring of diethylene glycol butyl ether, which plays an important role in protecting people's health and ecological environment safety.

In addition to the traditional chromatography-mass spectrometry technology, in recent years, the detection method of diethylene glycol butyl ether based on spectroscopy technology has attracted more and more attention. Near-infrared spectroscopy (NIR), as a fast, non-destructive and on-line analysis method, has the advantages of simple operation and fast analysis speed, and is widely used in the content determination and quality control of diethylene glycol butyl ether. By establishing the correlation model of diethylene glycol butyl ether and near infrared spectroscopy, the rapid detection and quantitative analysis of the content of diethylene glycol butyl ether in the sample can be realized, which provides convenience and efficiency for industrial production.

With the development of nanotechnology, the detection methods of diethylene glycol butyl ether based on nanomaterials are gradually mature. Studies have shown that some nanomaterials such as gold nanoparticles and graphene have high selectivity and sensitivity to diethylene glycol butyl ether, and can be detected with high sensitivity by surface enhanced Raman scattering (SERS). This detection method based on nanomaterials not only has the characteristics of high sensitivity and fast response, but also has the advantages of simple sample preparation and convenient operation, which provides a new idea and method for the rapid detection of diethylene glycol butyl ether.

With the continuous development and innovation of science and technology, the detection methods and analysis techniques of diethylene glycol butyl ether are constantly improving and expanding. Whether it is the traditional chromatography-mass spectrometry technology, or the emerging spectroscopy and nanotechnology, it provides strong technical support for ensuring product quality and promoting industrial upgrading. It is believed that with the further development of technology, the detection and analysis of diethylene glycol butyl ether will be more accurate and rapid, which will inject new power and vitality into the development of related industries.
