Abstract

The invention discloses a method for quantitatively measuring the RDX content by a correction irrelevant method (CIC method) of GC-AED (gas chromatography-atomic emission spectrometry). In a gas chromatographic analysis method disclosed by the invention, the used chromatographic column is: an HP-5 weakly polar capillary column, the sample inlet port temperature is 200 DEG C, the column temperaturebox is 170 DEG C, the diversion ratio is 20:1, the sample inlet amount is 0.5 muL and the column flow velocity is 3 mL / min. AED parameters are: the transmission line temperature is 220 DEG C and thecavity temperature is 250 DEG C; the used detection element is C and the wavelength is C193nm; the used reaction gas is O2, H2; and the gas pressure of the complementary gas He is 200 KPa. The RDX quantitative detection method disclosed by the invention comprises the following steps: analyzing DBP and RDX separately by a chromatographic analysis method, detecting the C element of the DBP and RDX by an AED detector (the detection wavelength is C193 nm), and calculating the C element content of the RDX by taking the C element content of the DBP as standard so as to obtain the compound content ofthe RDX. The element chromatographic analysis method has good peak shape, compound quantification adopts a non-self and non-energetic standard sample, the accuracy degree is high and the repeatability is high.
