本文介绍了微秒级脉冲辉光放电（PGD）直流模式在现有商用快流源质谱仪上的应用。与连续直流放电相比，PGD中的分析性能显著改善，以及离子的时间门控检测。本文介绍了微秒级脉冲辉光放电扇形场质谱仪在深度剖面分析中的成功应用。对PGD中样品离子的输运过程进行了实验和理论研究。
The application of microsecond Pulsed Glow Discharge (PGD) in direct current mode to existing commercial mass spectrometers with the Grimm type fast flow sources is described. Significant improvement of analytical properties in PGD, together with time gated detection of ions, in comparison with continuous direct current discharge is demonstrated. Successful application of microsecond pulsed glow discharge with a sector field mass spectrometer for depth profile analysis is shown. Processes of the sample ion transport in PGD are investigated experimentally and theoretically.
