建立了离子色谱法分析火灾烟气成分的方法。样品用去离子水和氢氧化钠溶液配制，采用0.45μm的滤膜过滤2～3次后，配制成样品溶液，稀释适当倍数后进样分析，采用电导检测器进行检测。各阴离子在1.0～50.0 mg／L范围内与色谱峰面积均呈现良好的线性关系，相关系数均大于0.999，方法的检出限在0.06～0.1 mg／L之间。方法的加标回收率在86.0%～110%之间，测定结果的相对标准偏差为0.5%～9.0%(n=5)。该方法简便快捷，选择性好，灵敏度高，可满足火灾烟气成分的分析要求。

A method for analysis of fire smoke components by ion chromatography was established. After the sample with deionized water and sodium hydroxide solution preparation,using 0.45μm membranefilter 2–3 times,the sample solution was diluted appropriately and detected by the conductivity detector. Various anions showed a good linear relationship with chromatographic peak areas in the range of 1.0–50.0 mg/L,the correlation coefficients were greater than 0.999,and the detection limits was 0.06–0.1 mg/L. The recoveries was 86.0%–110%,and the relative standard deviation of determination results was 0.5%–9.0%(n=5). The method is simple,good selectivity and high sensitivity, it can meet the requirements offire smoke components analysis.
