| 摘 要： | 介绍了两台自行研制的激光溅射离子源垂直引入式飞行时间质谱仪(LAI-oa-TOFMS),相比于其他固体样品直接分析法,该仪器具有样品预处理简单、样品更换速度快(数分钟)、可进行微区分析、谱图干扰峰少和绝对灵敏度高(10-15g级)等众多优点。两台质谱仪的最佳质量分辨率分别达到7 000和4 000(FWHM)。重点对比分析了不同样品的电离方式和离子传输系统对仪器性能的影响。

| Abstract: | Two sets of home-made laser ablation ionization time-of-flight mass spectrometers were introduced. These instruments compared to other solid sample direct analysis methods have many merits：easy pre-sampling, samples quick changing (only several minutes), ability for micro-space analysis, spectrum with few interference and very low absolute determination limit （1015g grade）. The best mass resolutions of these two mass spectrometers can achieve 7 000 and 4 000 (FWHM) respectively. The impacts of different sample introduction method and ion transmission system on instrument performances were also analyzed comparatively in this article. |
