Abstract

To established an effective GC-MS /MS method for the contents determination of the residual DEHP in injection equipment, and investigate the effect of the pretreatment on the measurement. To simulate the clinical conditions of use, under the condition of 37 degrees C balance extraction, extract liquor by chloroform extraction, then the extract followed by analysis of GC-MS /MS. The method was simple, rapid, sensitive and accurate. The limits of quantitation (LOQ, S/N = 5) of cyclohexanone was 0.075 μg/mL, The spiked average recoveries ranged from 92% to 98%. The relative standard deviations (RSDs) of the method ranged from 1.01% to 1.61%, The method was simple, fast, sensitive and accurate, and may serve as a mass control method for residual DEHP in injection equipment.
