New Green-Enriched Water Chromatography Provides Technical Support for Food Testing

[China Instrument Network Instrument R&D] A few days ago, information was obtained from the Inspection and Quarantine Bureau of Zhenjiang, Jiangsu Province. A Silver Nano-Lactose-bonded Silica-rich Water Chromatographic Stationary Phase and its preparation method was developed by Dr. Chen Tong, the Comprehensive Technology Center of the Bureau. Obtained national invention patents. The new environmentally friendly silver nano-lactose bonded silica gel-rich water chromatography provides technical support for food testing.

It is understood that the main objective of this patent is to address the current situation of abuse of chemical contaminants in the food field, and develop new environmentally friendly silver nano-lactose-bonded silica gel-rich water chromatography chromatographic packings for the development of polar additives and illegal additives. The rapid, high-throughput screening and detection technologies provide timely early warning and technical support for the risks associated with the illegal use of illegal additives in imported and exported food.

It is reported that Rich Water Chromatography is a green chromatographic separation technology, which inherits the advantages of hydrophilic interaction chromatography and can replace hydrophilic interaction chromatography to achieve the analysis and separation of polar compounds; and in the water-rich liquid chromatography mode, The mobile phase water content is usually greater than 90%, which greatly reduces the use of organic solvents, which not only protects the environment, but also reduces the physical injury to technicians. It can also greatly reduce the cost of testing, and it has many advantages.

Chromatography technology is commonly used in food testing, while the technology of the water-rich chromatographic stationary phase and its preparation method is mainly aimed at polar additives and illegal additives in foods, achieving high sensitivity, high analysis speed, and high detection accuracy. It will be a rare and excellent technical means for special food testing.
