This paper report the design parameters, construction and specificity of a small magnetic massspectrometer with an EI ion source, a sector magnetic analyser and a Faraday cup ion detector.
The spectrometer based on linear optical detector has the advantage of multi-spectrum channel detection and it plays an important role in mass-spectrometry.
