在线质谱仪与在线气相色谱仪的比较及应用

摘要

本文介绍了在线质谱仪和在线气相色谱仪的原理及结构,并根据各自的特点对其应用进行简单总结和比较。由于两者工作原理的差异,在线质谱仪具有更快的分析速度和定性能力,而在线气相色谱仪对成分复杂的气体可达到更好的分离效果,在日常维护中,两者也存在较大的差别。因此,在实际应用中,要考虑现场监测的需要来选择合适的仪器。%Main principles,configurations and applications of process mass spectrometer and on-line gas chromatograph are introduced in this article.Since the obvious difference in basic work principle,compared with online gas chromatograph,process mass spectrometer provides high analysis speed and stability.While,on-line gas chromatograph also shows obvious advantages in complex sample analysis.In the daily maintenance,there are also distinct characters about each other.Which instrument should be used for on-line analysis depends on the real application environment.
