Abstract:

A method of UPLC-MS-MS in multiple reaction monitoring (MRM) mode was developed for the qualitative and quantitative analysis of iodosulfuron-methyl-sodium in 9 substance including apple, spinach, shallot, wheat, bean, beef, chicken liver, fat and milk. The sample preparation was based on ultrasonic-assisted organic solvent extraction and GPC cleanup. The results showed that the method developed is easy, rapid and sensitive, and all of its linear range, recovery, precision and detection limit meet the requirement of residue analysis.

Key words: UPLC-MS-MS, iodosulfuron-methyl-sodium, pesticide residue
