摘　　要：用低压离子色谱法分析爆炸物中的ＮＨ＋４、Ｋ＋和ＮＯ－３及氟化物中的Ｆ－，进行了精密度、线性范围和回收率试验，ＲＳＤ为１．００％～２．４０％，相关系数γ为０．９９９０～０．９９９５，回收率在９５．０％～９８．０％之间，说明了低压离子色谱法作为案件分析中的一种方法是可行的。Low pressure ion chromatography(LPIC) was applied to analyze NH + 4, K + and NO - 3 in the exploders and F - in the fluoride. The precision, linearity and recovery tests were conducted. Variation coefficients(RSD) were among the range of 1.00%～2.40% with the correlation coefficients (γ) ranging from 0.999 0 to 0.999 5 and the recoveries between 95.0%～98.0%. Therefore, it can be concluded that LPIC is feasible in the cases investigation.
