| Abstract: | A simple,sensitive HPLC-ESI-MS method was optimized for quantitative analysis of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine（HMX）.Under negative ionization mode,acetic acid was chosen as additive and the ion,M＋CH3COO]-was used for selective ion monitoring（SIM）.Good sensitivity was achieved with low acetic acid concentration in the mobile phase and relatively low capillary temperature.The optimal concentration of ammonium acetate in mobile phase was 0.05mmol/L～0.2mmol/L,and the limit of detection was 0.05 ng/mL for HMX in standard solution. |
