Abstract: Objective:A GC-MS method was established for the determination of 21phthalate plasticizers in Ligustrazine Phosphate and Sodium Chloride Injection. Methods:The determin ation was performed on DB-5MS column at the flow rate of 1.0 mL·min-1 using helium as carrier gas, injector temperature was 260 ℃ by temperature programming. Electron impact(EI)ionization mode was used, MRM was used for quantity analysis, the assays of phthalates elasticizers in 3 batches Ligustrazine Phosphate and Sodium Chloride Injection were determined. Results: 21 kinds of phthalates could be completely separated under the condition of GC-MS. The linear ranges were 80~2 000 ng·mL-1. The limit of detection was more than 2 ng·mL-1 and average recoveries were 90.7%~97.1%. Conclusion:This work provided an effective, accurate, sensitive and simple method for the rapid detection of huge quantity of samples.
