Abstract

The invention relates to a determination method for migration components in an NEPE propellant bonding system used in the field of aviation fuels. The determination method comprises the following experimental steps: preparation of a to-be-detected sample; determination of detection objects and detection conditions; drafting of an external standard calibration curve; formation of a detection data list; etc. According to the method, a plurality of migration components in the NEPE propellant bonding system are detected, wherein the components comprise a plasticizer nitroglycerine (ND), a plasticizer butanetriol trinitrate (BTTN), an amine stabilizing agent (AD) and a curing catalyst triphenyl bismuth (TPB). The determination method is extensively applicable to qualitative and quantitative detection of a solid rocket and an energetic material used in space and missile technologies and can effectively reduce sample treatment risks, simplify the process of measurement and analysis, reduce data processing errors and save experimental expenses for detection. Moreover, the following advantages are obtained: the determination method is simple and practicable, experimental process is convenient to popularize, repeatability of detection data is good, and data processing is accurate and reliable.
