摘要
介绍一台气相色谱仪存在的问题,提出了将原1次注样方式改为2次注样及采用BF-9202色谱工作站软件等改造措施,改造前后的谱图及数据对比表明:改造后的气相色谱仪基线稳定、重复性好、灵敏度高、分析效能高,其最小检知浓度符合国家标准。
The renovating process for a gas chromatograph is introduced. The defections before the renovation are described and the comparison is made in the data and chro-matograms between before and after the renovation. In fact, the renovated device can fully meet the basic requirement; stable baseline, good repetitiveness, high sensibility, and high efficiency of analysis. The minimum detecting concentration meets the national standard.
