Using relatively simple analog circuitry, and an inexpensive analog frequency modulated tape recorder (or a modified audio recorder) for data storage, repetitively scanned spectra may be examined on an oscilloscope, and reconstructed mass chromatograms produced. The same equipment may be used for peak matching, and for selective ion detection over the full mass range of a sector instrument.
利用相对简单的模拟电路以及一台廉价的模拟调频磁带录音机（或经过改装的音频录音机）来存储数据，就可以在示波器上检查重复扫描的光谱，并生成重建的质量色谱图。同样的设备可用于峰匹配以及在扇形仪器的整个质量范围内进行选择性离子检测。
