^(13)C质谱仪自动进样器的研制

Development of an autosampler for ^(13)C mass spectrometer

介绍了自行研制的13 C质谱仪自动进样器的工作原理、结构和性能。与手动进样器比较 ,采用自动进样器的13 C质谱仪的分析速度和精度分别由原来的 2 0 0s和 4× 10 -4提高到 15 0s和 1× 10 -4。

The working principle, configuration and performance of an autosampler of 13 C mass spectrometer used for expiration gas analysis are described. The application of the autosampler has increased the precision of measurement from 4×10 -4 to 1×10 -4 and shortened the analysis time from 200s to 150s.
