Rapid Determination of Acetone Residual in Central Control of Cefazolin Sodium by GC
A reasonable method for the determination of acetone was developed.The method used GC direct injection method,FID detector,carrier gas was nitrogen,injection volume was 1 μL,flow rate was 1.5 mL/min,split ratio was 20 ∶ 1,injection port temperature was 200℃,detector temperature was 250℃,temperature programming operation was 18.833 min.All the verifications meet the requirements,the operation is simple and the sensitivity is high.This method can be used for rapid and accurate determination of the content of controlled acetone in cefazolin sodium.
