AI Technical Summary

Technical Problem

Existing methods for detecting mercury content in beef and mutton are time-consuming and difficult to implement rapidly.

Method used

Supercritical fluid chromatography was used for separation and detection, combined with atomic fluorescence spectrometry. Supercritical carbon dioxide was used as mobile phase A, and a methanol-ethanol mixture was used as mobile phase B. Gradient elution was used, with a flow rate of 3 ml/min, a column temperature of 39 °C, and a back pressure of 1600 psi. Detector parameters were optimized to achieve rapid detection.

Benefits of technology

This method enables accurate and rapid detection of mercury compounds in beef and mutton within minutes, significantly reducing detection time compared to traditional methods while ensuring the accuracy and reliability of the results.

Abstract

The present application belongs to the technical field of food detection, and particularly relates to a rapid detection method of mercury content in beef and mutton. Based on the high-efficiency separation capacity of a supercritical fluid chromatograph, the present application can rapidly and accurately separate methyl mercury and ethyl mercury to be detected, and then transport them to a subsequent atomic fluorescence spectrometer for rapid, accurate and reliable detection. Compared with the separation and detection of a common high-efficiency liquid chromatograph, the present application saves a large amount of detection time under the premise of ensuring accurate and reliable detection results, realizes the purpose of rapid detection, is beneficial to the control of mercury content, and has important significance for the field of food safety.
