在试验研究的基础上 ,建立了火场残留无痕迹助燃剂丙酮的定性鉴定和定量测定技术。分析鉴定技术简单 ,易操作。从火场残留物样品中丙酮的分离提取、利用化学计量学的方法制作标准曲线回归方程、求相关系数 ,到丙酮的定性鉴定、定量分析 ,介绍了火场残留助燃剂丙酮的提取检验技术的全过程 On the basis of experimental research, the qualitative identification and quantitative determination of acetone, an unmarked combustion improver in the fire field, were established. Analysis and identification technology is simple, easy to operate. From the fire residue samples of acetone separation and extraction, the use of chemometrics method for the production of standard curve regression equation, correlation coefficient, to the qualitative identification of acetone, quantitative analysis of the fire residue combustion agent acetone extraction and detection of the whole process
