【摘要】：为缩短叠氮硝胺吸收药组分定量分析时间,采用压延烘干法制备了样品,并与过筛烘干法制备的样品进行了比较。用液相色谱法、卡尔·费休法分别检测了两种样品的组分含量和水分含量。结果表明,压延烘干法制备样品共需要1.2h,明显少于过筛烘干法的4.5h。压延烘干法制得的样品均匀性更好,使得取样量可以由过筛烘干法的2g减少到0.2g,配制试样溶液时所需的溶剂体积减少了90%。压延烘干后的样品含水质量分数为0.06%~0.12%,低于过筛烘干法制备的样品。表明用压延烘干法制备样品,可以减少样品组分定量分析的总时间,并且可以减少废溶剂量。
[Abstract]:In order to shorten the quantitative analysis time of azido nitramine absorption component, the sample was prepared by the method of calender drying and compared with the sample prepared by the method of screening and drying. The composition and moisture content of two samples were detected by liquid chromatography and Carle Fischer method respectively. The results showed that the sample prepared by the method of calendering and drying was 1.2h. The uniformity of the sample prepared by the 4.5h. calender drying method less than the drying method makes the sampling amount can be reduced from 2G to 0.2g by the sieving drying method. The volume of the solvent required for the preparation of the sample solution reduces the content of the water content of the sample after the 90%. calendering and drying to 0.06%~0.12%, which is lower than the sample prepared by the sieving drying method. The preparation of samples by drying method can reduce the total time of quantitative analysis of sample components and reduce the dissolving dose.
