利用常压直流等离子体作为离子源，对从喷雾器中引入的溶液进行了直接分析。离子从等离子体中提取到真空系统中，并聚焦到四极杆质量分析仪中。获得了单电荷离子的高产率和小的能量扩散，并观察到溶液组分的清晰光谱。介绍了该方法，并给出了简单解的观察结果。该方法对许多元素的灵敏度表明，似乎与其他痕量分析方法相当。
The use of an atmospheric pressure d.c. plasma as an ion source has been explored for the direct analysis of solutions introduced into it from a nebuliser. Ions are extracted from the plasma into a vacuum system and are focused into a quadrupole mass analyser. A high yield of singly charged ions with a small energy spread is obtained and clear spectra of the constituents of the solution are observed.The method is described and the results observed on simple solutions are given. The sensitivity of the method for a number of elements is indicated and appears to be comparable with other trace-analysis methods.
