本文报道了将电感耦合等离子体（ICP）离子源与傅里叶变换离子回旋共振（FTICR）质谱仪相结合所获得的初步结果，沿着得到的光谱显示出亚毫克/升的检测限和高质量分辨率（质量分辨率，m/Δm10%V = 7000− 10000）。还示出了具有λ分辨能力（m/Δm10%V = 88 000）的ICP-FTICR光谱。这两个仪器配置用于进行这项工作，一个在佛罗里达大学，和其他在国家高磁场实验室，进行了说明。还包括简明的结果，从计算机辅助干扰的研究，旨在枚举质谱干扰需要质量分辨能力超过10 000。
Initial results obtained by incorporation of an inductively coupled plasma (ICP) ion source with a Fourier transform ion cyclotron resonance (FTICR) mass spectrometer are reported, along with spectra which demonstrate sub-milligram-per-liter detection limits and high mass resolution (mass resolving power, m/Δm10%V = 7000−10 000). Also shown is an ICP-FTICR spectrum with ultrahigh resolving power (m/Δm10%V = 88 000). Both instrumental configurations used to conduct this work, one at the University of Florida, and the other at the National High Magnetic Field Laboratory, are described. Also included are concise results from a computer aided interference study designed to enumerate mass spectral interferences requiring mass resolving power in excess of 10 000.
