Abstract

In recent years, food safety has attracted great attention. Some lawbreakers use β-Agonists to increase the lean meat rate of livestock, and human intake of a certain amount of β-Agonists can cause damage to the nervous system. After being ingested by livestock, β-Agonists is distributed to tissues throughout the body through blood circulation, and some metabolites are excreted into urine through the kidneys. Therefore, the residual amount of β-Agonists in urine can indirectly reflect the drug exposure level in livestock. This paper detects five types of β-Agonists in pig urine samples based on a portable mass spectrometer. The detection concentration reaches 50 ng/mL, and the signal-to-noise ratio (S/N) is greater than 3, verifying the feasibility of portable mass spectrometry in the detection of complex biological samples.
