便携式气相色谱仪的研制及应用

Development and Application of Portable Gas Chromatograph

介绍了便携式气相色谱仪的原理和结构,研究了温度对该仪器测定结果的准确度和检出限的影响。实现一次进样,双柱双检测器快速检测。混合样品的分析时间小于2min,连续进样时定性重复性的相对标准偏差小于1%(n=6)。该仪器可方便、快速、有效测试并分析环境空气和污染源的组分。

The paper introduces the principle and structure of the self-developed portable chromatograph,studies the temperature on the accuracy of the determination result of the instrument and studies the impact on the limit of the check out,realizes one time sampling,quick detection of double pillars and double detectors.The analytical time of the mixed sample is less than 2 minutes,and the relative standard deviation of the qualitative repeat is less than 1%(n=6)as continuous sampling.The portable gas chromatograph is ease,quick and affective testing and analyzes the components of environmental air and pollution sources.
